The Significance of Data Backup

In the era of information, data stands as the backbone of virtually every software application. Whether it’s a user’s preferences in a mobile app or financial records in an enterprise system, data forms the core of functionalities. However, with great power comes the responsibility of safeguarding this data against various threats such as hardware failures, cyberattacks, and human errors. This is where data backup steps in as a savior.

1. Data Integrity and Recovery

Data loss can be catastrophic, potentially resulting in financial losses, legal ramifications, and loss of trust among users. Backup solutions ensure data integrity by creating copies of essential information at regular intervals. In case of data corruption or loss, these backups act as recovery points, enabling developers to restore the application to a previous state.

2. Disaster Recovery

Natural disasters, hardware failures, or even simple human errors can disrupt the availability of applications. Data backup plays a pivotal role in disaster recovery, allowing organizations to rebuild their applications and services with minimal downtime.

Areas, Partial Views and Child Actions in ASP.NET MVC

Developers may organise their applications, build modular components, and improve code reuse by using Areas, Partial Views, and Child Actions in ASP.NET MVC. Let’s examine each of these ideas and how to employ them successfully:

Areas in ASP.NET MVC:

A huge ASP.NET MVC application can be divided up into manageable portions using areas. Within the application, each region represents a different functional area. You may designate several locations for the administration, user dashboards, or public-facing pages, for instance.

Right-click the project, pick “Add,” and then select “Area” from the context menu to create an area. Following that, you can give the region a name and designate a folder structure for it. It will have separate folders for its controllers, views, and models.

Areas facilitate better concern segregation and simplify the upkeep of sophisticated programmes.

Partial Views in ASP.NET MVC:

In order to display a portion of HTML content and C# code in various views throughout the application, partial views are reusable components.

You can build a partial view by adding a new view to the “Views” folder (or a subfolder) and naming it something like “_PartialView.cshtml.”

You can render a partial view within another view using the @Html.Partial or @Html.RenderPartial methods, passing the partial view’s name as an argument.

Child Actions in ASP.NET MVC:

Child actions are controller methods that return partial views. They come in handy when you need to render different elements of a view independently.

To create a child action, define a method in a controller that returns a PartialViewResult. You can use the ChildActionOnly attribute to ensure that the method can only be called as a child action and not directly as an HTTP request.

In your main view, you can call the child action using the @Html.Action or @Html.RenderAction methods, passing the name of the child action and any required parameters.

Advantages of utilising areas, partial views, and child actions

Utilizing areas, partial views, and child actions in ASP.NET MVC provides several advantages that can significantly enhance the development process and improve the overall architecture of your application. Here are some key benefits of using these features:

Modularity and Reusability:

Areas allow you to divide a large application into smaller functional sections, promoting modularity and separation of concerns. Each area can have its own set of controllers, views, and models, making it easier to manage and maintain specific features.

Partial views encapsulate reusable components, such as navigation bars, headers, footers, or widgets. Once created, you can include them in multiple views across the application, reducing duplication of code and promoting reusability.

Organization and Maintainability:

By structuring your application with areas, you create a clear organization that improves code maintainability and makes it easier for developers to navigate and understand the application’s structure.

Partial views and child actions help to decompose complex views into smaller, manageable components. This separation of concerns leads to cleaner code and makes it easier to maintain and update specific parts of a page independently.

Code Separation and Readability:

Areas encourage the separation of different functional parts of the application, reducing code coupling and increasing code readability.

Partial views and child actions enable you to separate the presentation logic from the main view, enhancing the readability and maintainability of the code.

Code Reusability and DRY Principle:

Areas, partial views, and child actions promote the “Don’t Repeat Yourself” (DRY) principle, allowing you to reuse code across different areas or views.

Instead of duplicating code for common UI components, you can create partial views once and then use them in multiple views, reducing development effort and avoiding inconsistencies.

Performance Optimization:

By utilizing child actions, you can optimize the rendering of complex views by rendering specific parts of a page separately, reducing the overall load time and enhancing user experience.

Partial views can help optimize rendering performance by allowing you to cache the output of specific components that are unlikely to change frequently.

Enhanced Testing and Debugging:

The use of areas allows for better isolation and targeted testing of specific functional sections, making unit testing and debugging more focused and effective.

Partial views and child actions can be tested independently, making it easier to verify the correctness of individual components.

In summary,, the strategic use of areas, partial views, and child actions in ASP.NET MVC not only fosters reusability, performance optimisation, and increased testing capabilities but also enhances code organisation and maintainability. Building scalable, stable, and modular web applications that are simpler to maintain and develop over time is made possible by these qualities.

Example

Consider the following scenario:

Assume you have an e-commerce site with distinct sections for the product catalogue and the user dashboard. You can construct partial views for common elements such as navigation, headers, and footers and then reuse them across several views inside each section. You can also call a child action in the header partial view to display the user’s shopping basket.

You may improve the flexibility and maintainability of your ASP.NET MVC application by efficiently utilising Areas, Partial Views, and Child Actions, resulting in a more organised and efficient development process.

Routing in ASP.NET

Routing in ASP.NET is the process of sending HTTP requests to the appropriate controller. Whether a request should be forwarded to the controller for processing or not is up to the MVC middleware. This choice is made by the middleware based on the URL and some configuration data.

In other words, routing in ASP.NET is a mechanism that allows you to define URL patterns and map them to specific resources or handlers in your web application. It enables you to create clean, user-friendly URLs that are more meaningful and descriptive than traditional query-string based URLs.

Routing is an essential part of the ASP.NET MVC (Model-View-Controller) framework and the newer ASP.NET Core framework, although the concept remains similar across both technologies.

Routing’s main goal is to separate your web application’s physical file structure from its URL structure. In the past, URLs in web applications were linked to particular physical server files (for example, a particular.aspx page). However, routing gives you more flexibility when defining the URLs for your web application since it allows you to specify URL patterns and link them to controllers and actions (in MVC) or endpoints (in ASP.NET Core).

To address various scenarios and requirements, ASP.NET MVC supports a number of different forms of routing. The primary routing types that ASP.NET MVC supports are listed below:

Conventional Routing: In ASP.NET MVC, conventional routing is the default routing method. The mapping of URL segments to names of controller and action method uses a pattern-based technique. A URL pattern typically looks like this: “controller/action/id,” where “controller” and “action” stand in for the names of the controller and action method, respectively. It is possible to omit the “id” parameter.

Here’s a basic example of routing in ASP.NET MVC:

// In the RouteConfig.cs file (MVC) public static void RegisterRoutes(RouteCollection routes) {     routes.IgnoreRoute(“{resource}.axd/{*pathInfo}”);     routes.MapRoute(         name: “Default”,         url: “{controller}/{action}/{id}”,         defaults: new {controller = “Home”, action = “Index”, id = UrlParameter.Optional }     ); }

In this example, a default route is defined with a pattern like “{controller}/{action}/{id}”. When a user visits a URL like “example.com/Home/Index”, the routing system will map it to the “Index” action method in the “HomeController” within the MVC application. The “id” parameter is optional and can be omitted in the URL.

ASP.NET Core uses a similar concept of routing, but the syntax and configuration are slightly different. Here’s a basic example of routing in ASP.NET Core:

// In the Startup.cs file (ASP.NET Core) public void Configure(IApplicationBuilder app, IWebHostEnvironment env) {     // Other middleware configurations…     app.UseRouting();     app.UseEndpoints(endpoints =>     {         endpoints.MapControllerRoute(             name: “default”,             pattern: “{controller=Home}/{action=Index}/{id?}”         );     }); }

In this example, the UseRouting() method is called to enable routing, and then MapControllerRoute() is used to define the default route pattern.

Routing plays a crucial role in creating clean and SEO-friendly URLs, improving the maintainability of your web application, and supporting more structured and organized code through the proper separation of concerns.

Attribute Routing: Using attributes, you may build routes directly on the controller and action methods. This method gives you more fine-grained control over single action routing and allows you to build unique routes for individual actions. When you have non-conventional URL patterns or want more descriptive URLs, attribute routing comes in handy.

In ASP.NET MVC, here’s an example of attribute routing:

// Controller with attribute routing [RoutePrefix(“products”)] public class ProductController : Controller {     [Route(“”)]     public ActionResult Index()     {         // Action logic     }     [Route(“{id}”)]     public ActionResult Details(int id)     {         // Action logic     } }

Area Routing: Areas are used in ASP.NET MVC to partition related portions of a web application into different modules. Controllers, views, and models can be customised for each region. Area-specific routing can be used with areas to control routes inside that specified area. When dealing with large and complex applications, this helps to maintain clean and organised code.

Custom Route Constraints: Custom route constraints let you specify extra requirements that a route must meet in order to be accepted as a match. Implementing the IRouteConstraint interface enables you to create unique route constraints. For instance, you can build a custom constraint to guarantee that the “id” argument adheres to a particular format or fits within a given range.

Catch-All Routes: Any URL that doesn’t match one of the other defined routes is matched using catch-all routes. When dealing with specific URL patterns that don’t suit the typical route patterns, this is useful.

With these multiple routing systems in ASP.NET MVC, you may handle a variety of URL patterns, create custom routes, and set up your application’s URLs anyway you see fit.

Three Tier Architecture in MVC

Three Tier (Three Layer) Architecture

With a three-layer design, the project is divided into three layers: the user interface layer, the business layer, and the data layer (database), where we divide the UI, logic, and data into three groups. If a user wants to switch the user interface from a Windows computer to a smartphone, he or she simply needs to alter the UI layer; all other layers are unaffected. Like this, if a user wishes to change a database, he simply needs to update the data layer; everything else stays the same.

The widely used three-tier (or three-layer) architecture is a way to organise the codebase. This architecture divides the codebase into three distinct levels, each with a unique set of duties:

Presentation layer: This is the application’s user interface, which shows the user the features and data of the programme.

Business logic (or Application) layer: The business logic that powers the application’s essential features is contained in this layer. as processing the data moving between the other two layers and making judgements, calculations, and evaluations.

Data access layer (or Data) layer: To save and recover application data, this layer communicates with databases.

Advantages of using three-tier architecture are:

Accelerated development: Reducing product time to market and enabling developers to use the most current tools and layer appropriate languages.

Improved scalability:  By deploying apps on many levels, each tier may always be scaled separately.

Improved Reliability: By using several tiers, you may execute additional components of your application on other servers and employ results that have been cached to improve reliability and availability.

Enhance security: By using a well-designed application layer as a private firewall to help avoid receptive weaknesses like SQL injection.

The package of different layers is as follows.

• Presentation Layer – controller package
• Business Logic Layer – service package
• Data Access Layer – repository package 

Three Layer Architecture using MVC Sample:

Create an empty MVC web application project with Project name “WebApp” and solution name “TLA”. This WebApp project is the presentation layer.

In Solution TLA, add a new project to create business logic à Class library (.net framewok) à name the project as BusinessLayer.

Again, in Solution TLA, add a new project to create data access à Class library (.net framewok) à name the project as DataBaseLayer.
Add BusinessLayer & DataBaseLayer as reference in “WebApp”.

Add BusinessLayer as reference in “DataBaseLayer”.

In sql server explorer, add a new database with name “MYDB” and create a table with name “Registration”.

CREATE TABLE [dbo].[Registration]( [RegId] [int] IDENTITY(1,1) NOT NULL, [FullName] varchar NULL, [Address] varchar NULL, [Gender] varchar NULL, [City] varchar NULL, [DoB] [date] NULL, [Cno] varchar NULL, PRIMARY KEY CLUSTERED ([RegId] ASC)

In “DataBaseLayer”, add the model file using “ado.net entity data model”.

Once model is created, copy the connection string from app.config of “DataBaseLayer” and paste it in web.config of “WebApp”.

In “BusinessLayer”, create a class file with name “RegistrationModel” and replace with below snippet.

public class RegistrationModel { public int RegId { get; set; } public string FullName { get; set; } public string Address { get; set; } public string Gender { get; set; } public string City { get; set; } public Nullable DoB { get; set; } public string Cno { get; set; } }

In “DataBaseLayer”, add a new folder with name “DBOperation”, in it, add a class file with name “ManageRegistration” and replace with below snippet.

public class ManageRegistration { public void AddReg(RegistrationModel regModel) { using (var DB = new MYDBEntities()) { Registration Reg = new Registration() { FullName = regModel.FullName, Address = regModel.Address, Gender = regModel.Gender, City = regModel.City, DoB = regModel.DoB, Cno = regModel.Cno }; DB.Registrations.Add(Reg); DB.SaveChanges(); } } }

Then add EntityFramework.dll and EntityFramework.SqlServer.dll references in “WebApp”.

So now the business layer and data layer has been completely created.

Now, in WebApp (i. e. in presentation layer), add a new controller with name “Home controller” and replace with below snippet.

public class HomeController : Controller { // GET: Home public ActionResult Index() { return View(); } ManageRegistration ManageReg = new ManageRegistration(); [HttpPost] public void AddReg(FormCollection Form) { RegistrationModel registrationModel = new RegistrationModel() { FullName = Form["txtName"], Address = Form["txtAddress"], Gender = Form["rdbGender"], City = Form["txtCity"], DoB = Convert.ToDateTime(Form["txtDoB"]), Cno = Form["txtCno"] }; ManageReg.AddReg(registrationModel); Response.Write("Saved"); } }

Add index view with empty without model and put the below html and ajax snippet in it

Run the program

Stored Procedure in SQL Server

• A stored procedure is a precompiled and stored database object that contains a set of SQL statements and procedural logic that can be executed as a single unit. It can be used in a database management system to simplify complex queries and database operations. It is a prepared SQL code that you can save, so the code can be reused over and over again. Stored procedures help improve performance and security, as well as simplify the code.

Here’s a basic example of a stored procedure that accepts two input parameters and returns the sum of those two numbers:

CREATE PROCEDURE AddNumbers @n1 INT, @n2 INT AS BEGIN SET NOCOUNT ON; SELECT @n1 + @n2 AS ‘Sum’; END

In this example, CREATE PROCEDURE is used to define the name of the procedure (AddNumbers) and its input parameters (@n1 and @n2). The AS keyword is used to begin the code block for the stored procedure.

SET NOCOUNT ON is used to prevent the count of the number of rows affected by the stored procedure from being returned.

The code block then calculates the sum of the two input parameters and returns the result using the SELECT statement.

Once the stored procedure is defined, it can be executed by calling its name:

EXEC AddNumbers 2, 3;

This will return the result 5 as the sum of 2 and 3.

Stored Procedure in a Basic CRUD Operation

Now, let us have an idea about using stored procedure in a basic CRUD operation sample.

Let us create a database as follows:

Create database Company

Then create a table in the corresponding database.

CREATE TABLE Employee( EmpCode int, EmpName nchar(100), EmpAge int, EmpSal int)

Inserting data into a table: This stored procedure inserts a new employee record into a table named Employee:

CREATE PROCEDURE AddEmployee @EmpCode int, @EmpName nchar(100), @EmpAge int, @EmpSal int AS BEGIN SET NOCOUNT ON; INSERT INTO Employee(EmpCode, EmpName, EmpAge, EmpSal) VALUES (@EmpCode, @EmpName, @EmpAge, @EmpSal); END

On executing the above snippet, a stored procedure to add the details in the table will be created.

Now, by calling the below query, the table will get added the following 5 datas.

EXEC AddEmployee 1, ‘TOM’, 25, 30000 EXEC AddEmployee 2, ‘RAM’, 25, 30000 EXEC AddEmployee 3, ‘RAJA’, 26, 32000 EXEC AddEmployee 4, ‘SIVA’, 26, 32000 EXEC AddEmployee 5, ‘GOPI’, 25, 30000

Retrieving data from a table: This stored procedure retrieves all the rows from a table named Employee:

CREATE PROCEDURE GetEmployees AS BEGIN SET NOCOUNT ON; SELECT * FROM Employee; END

On executing the above snippet, a stored procedure to get the employee details from the table will be created.

Then by simply calling the below query, the datas stored in the table can be retrieved.

EXEC GetEmployees

Updating data in a table: This stored procedure updates an existing employee record in a table named Employee:

CREATE PROCEDURE UpdateEmployee @EmpCode int, @EmpName nchar(100), @EmpAge int, @EmpSal int AS BEGIN SET NOCOUNT ON; UPDATE Employee SET EmpName = @EmpName, EmpAge = @EmpAge, EmpSal = @EmpSal WHERE EmpCode = @EmpCode; END

On executing the above snippet, a stored procedure to update the details in the table will be created.

Now, by calling the below query, the data with “EmpCode =1” in the table can be updated with new data as follows.

EXEC UpdateEmployee 1, ‘Jerry’, 26, 32000

Deleting data from a table: This stored procedure deletes an existing employee record from a table named Employee:

CREATE PROCEDURE DeleteEmployee @EmpCode int AS BEGIN SET NOCOUNT ON; DELETE FROM Employee WHERE EmpCode = @EmpCode; END

On executing the above snippet, a stored procedure to delete the details in the table will be created.

Now, by calling the below query, the data with “EmpCode=1” in the table can be deleted

EXEC DeleteEmployee 1

These are just a few examples, and there are many more possibilities for what you can do with stored procedures.

SQL & C# Dot Net – Online Training in India:

SQL and DOT NET Technologies:

SQL and DOT NET are two distinct technologies that are frequently used in software development. SQL is an abbreviation for Structured Query Language, a programming language used to manage and manipulate relational databases. DOT NET is a software development framework that allows you to create and run applications on a variety of platforms, including Windows, macOS, and Linux.

SQL is widely used in relational databases such as MySQL, Oracle, and Microsoft SQL Server to manage data. SQL allows developers to use a standardised syntax to create, modify, and query databases. SQL allows for a wide range of operations, such as data insertion, deletion, modification, and retrieval. SQL is also used to analyse data, report on it, and gather business intelligence.

DOT NET is a well-known software development framework that is used to create desktop, web, and mobile applications. DOT NET provides a set of libraries, tools, and runtime environments that simplify the development, testing, and deployment of applications. DOT NET supports a variety of programming languages, including C#, F#, and Visual Basic, and it can be used to create applications for a variety of platforms, including Windows, macOS, Linux, and mobile devices.

SQL and DOT NET, when used together, can provide powerful solutions for managing and manipulating data in applications. For example, a DOT NET application can use SQL to manage its data in a relational database, making it easier to store and retrieve data. Furthermore, DOT NET includes a set of libraries and tools that make it easier to integrate with SQL databases, allowing developers to create applications that can handle large amounts of data while also supporting complex data analysis and reporting.

Future of DOT NET:

Dot Net has a broad scope, and its future appears bright. Dot net is the future of Windows and other operating systems development.

It is a comprehensive framework for developing large enterprise-scale and scalable software applications.

Dot Net is a modern, flexible, fast, and secure technology that integrates well with other technologies.

“c++” is the result of the evolution of “c.” C++’s evolution continues. C# is a modern, dependable, and robust programming language. C#.net works with the Microsoft.NET framework. Delegates, Interface, and Abstraction are just a few of the cool features that have propelled C#.net to the top of the world. C# has inherited the best characteristics of its forefathers, including C, C++, and Java. Because of their best features, C# continues to be the solution provider for various hypothetical problems. C#.net was derived from various object-oriented programming extracts.

OOPs Concepts

OOPs Concepts:

It is a programming paradigm that focuses on the use of objects to represent data and behaviors in software applications.

It is based on the concept of “classes” and “objects”.

The main principles of OOPs are Encapsulation, Inheritance, Polymorphism & Abstraction

Classes:
A class is a blueprint for creating objects. It defines the properties and methods that an object of that class will have. For example, a class called “Person” might have properties such as “name”, “age”, and “gender”, and methods such as “walk” and “talk”.

In C#, classes are a fundamental building block of object-oriented programming (OOP). A class is a blueprint or a template that defines the structure and behaviour of a particular type of object.

Here’s an example of a class in C#:

public class Person

{

    public string Name { get; set; }

    public int Age { get; set; }

    public string Address { get; set; }

    public void PrintDetails()

    {

        Console.WriteLine($”Name: {Name}, Age: {Age}, Address: {Address}”);

    }

}

In this example, we have defined a class called Person that has three properties: Name, Age, and Address. These properties are defined using auto-implemented properties, which are shorthand for defining a private field and public getter/setter methods.

The PrintDetails method is a behaviour of the Person class. It is a public method that can be called on an instance of the Person class to print out the person’s details.

To create an instance of the Person class and set its properties, we can do the following:

Person person = new Person();

person.Name = “John”;

person.Age = 30;

person.Address = “123 Main St.”;

And to call the PrintDetails method on the person instance:

person.PrintDetails(); // Output: Name: John, Age: 30, Address: 123 Main St.

In this way, classes in C# allow us to define the structure and behaviour of our objects and create instances of those objects with specific properties and methods.

Objects:

An object is an instance of a class. It represents a specific instance of the class and has its own set of values for the properties defined by the class. For example, an object created from the “Person” class might have a name of “John”, an age of 25, and a gender of “Male”.

In C#, an object is an instance of a class. When we create an instance of a class using the new keyword, we are creating an object of that class.

Here’s an example of creating an object of the Person class we defined earlier:

Person person = new Person();

In this example, person is an object of the Person class. We can access its properties and call its methods using the dot notation:

person.Name = “John”;

person.Age = 30;

person.Address = “123 Main St.”;

person.PrintDetails(); // Output: Name: John, Age: 30, Address: 123 Main St.

Each object of a class has its own set of properties and can have different values for those properties. For example, we can create another object of the Person class with different values for its properties:

Person person2 = new Person();

person2.Name = “Jane”;

person2.Age = 25;

person2.Address = “456 Elm St.”;

person2.PrintDetails(); // Output: Name: Jane, Age: 25, Address: 456 Elm St.

In this way, objects in C# allow us to create multiple instances of a class, each with its own set of properties and values. We can use these objects to represent real-world entities or concepts in our programs and manipulate them by calling their methods and accessing their properties.

Encapsulation:

One of the key features of OOP is encapsulation, which is the concept of bundling data and methods that operate on that data within a single unit. This makes it easier to manage and maintain the code and helps to prevent the data from being accessed or modified by code outside of the class.

Encapsulation is one of the core principles of object-oriented programming (OOP) and refers to the practice of bundling data and the methods that operate on that data within a single unit, called a class, and restricting access to the inner workings of that class from the outside world.

In C#, encapsulation is achieved through access modifiers, which are keywords that determine the level of access that other code has to a particular class member (i.e., fields, properties, methods). C# provides four access modifiers:

public: The member is accessible from any code.

private: The member is accessible only within the same class.

protected: The member is accessible within the same class and any derived classes.

internal: The member is accessible within the same assembly.

Here’s an example of using encapsulation to hide the implementation details of a Person class:

public class Person

{

    private string name;

    private int age;

    private string address;

    public string Name

    {

        get { return name; }

        set { name = value; }

    }

    public int Age

    {

        get { return age; }

        set { age = value; }

    }

    public string Address

    {

        get { return address; }

        set { address = value; }

    }

    public void PrintDetails()

    {

        Console.WriteLine($”Name: {Name}, Age: {Age}, Address: {Address}”);

    }

}

In this example, the fields name, age, and address are marked as private, which means they can only be accessed from within the Person class. However, we’ve also defined public properties Name, Age, and Address that provide access to these fields from outside the class. By using properties, we can control the access to the fields and add logic to the getter/setter methods if necessary.

The PrintDetails method is also a public method that can be called from outside the class to print out the person’s details. However, it does not provide direct access to the internal fields.

By using encapsulation in this way, we can ensure that the internal state of a class is not accidentally or intentionally modified from outside the class, and that changes to the internal implementation of the class do not affect the external code that uses it.

Inheritance:

Inheritance allows a new class to be based on an existing class, inheriting its properties and methods. This can save time and effort in development, as the new class can reuse the code of the existing class.

Inheritance is another core principle of object-oriented programming (OOP) and refers to the ability of a class to inherit properties and behaviours from a parent class. In C#, inheritance is achieved through the : symbol followed by the name of the parent class.

Here’s an example of using inheritance to create a Student class that inherits from the Person class:

public class Student : Person

{

    public int GradeLevel { get; set; }

    public string SchoolName { get; set; }

    public void PrintSchoolInfo()

    {

        Console.WriteLine($”School: {SchoolName}, Grade: {GradeLevel}”);

    }

}

In this example, the Student class inherits from the Person class using the: symbol. This means that the Student class has access to all of the public and protected members of the Person class, including its fields, properties, and methods.

In addition to the inherited members, the Student class defines two new properties, GradeLevel and SchoolName, and a new method, PrintSchoolInfo.

We can create an object of the Student class and set its properties just like we did with the Person class:

Student student = new Student();

student.Name = “John”;

student.Age = 15;

student.Address = “123 Main St.”;

student.GradeLevel = 9;

student.SchoolName = “High School”;

And we can call methods from both the Person and Student classes on the student object:

student.PrintDetails(); // Output: Name: John, Age: 15, Address: 123 Main St.

student.PrintSchoolInfo(); // Output: School: High School, Grade: 9

By using inheritance in this way, we can reuse code from existing classes and create more specialized classes that add new properties and behaviours on top of the existing ones. It also allows us to create a hierarchy of related classes, where each class builds on the properties and behaviours of the classes above it in the hierarchy.

Polymorphism:

Polymorphism allows objects of different classes to be treated as if they are of the same class, by using a common interface. This makes it easier to write code that works with multiple objects, as the code can be written to work with the interface rather than the specific classes.

Polymorphism is another core principle of object-oriented programming (OOP) and refers to the ability of objects of different classes to be used interchangeably in the same context. In C#, polymorphism is achieved through inheritance and interfaces.

There are two main types of polymorphism in C#: compile-time polymorphism and runtime polymorphism.

Compile-time polymorphism, also known as method overloading, refers to the ability of a method to have multiple definitions with different parameter lists. The correct method to call is determined at compile time based on the number and types of arguments passed to the method.

Here’s an example of method overloading in C#:

public class Calculator

{

    public int Add(int x, int y)

    {

        return x + y;

    }

    public float Add(float x, float y)

    {

        return x + y;

    }

}

In this example, the Calculator class defines two Add methods with different parameter types (int and float). Depending on the arguments passed to the Add method, the compiler will choose the appropriate overload at compile time.

Runtime polymorphism, also known as method overriding, refers to the ability of a subclass to provide a different implementation of a method that is already defined in its parent class. The correct method to call is determined at runtime based on the type of the object that the method is called on.

Here’s an example of method overriding in C#:

public class Animal

{

    public virtual void MakeSound()

    {

        Console.WriteLine(“The animal makes a sound.”);

    }

}

public class Dog : Animal

{

    public override void MakeSound()

    {

        Console.WriteLine(“The dog barks.”);

    }

}

In this example, the Animal class defines a virtual MakeSound method that can be overridden by its subclasses. The Dog class overrides the MakeSound method and provides a different implementation that prints “The dog barks.” to the console.

We can create objects of both the Animal and Dog classes and call the MakeSound method on them:

Animal animal = new Animal();

Dog dog = new Dog();

animal.MakeSound(); // Output: The animal makes a sound.

dog.MakeSound(); // Output: The dog barks.

By using polymorphism in this way, we can write code that is more flexible and adaptable to different types of objects, without having to know the exact type of the object at compile time. This makes our code more modular and easier to maintain over time.

Abstraction:

Abstraction is the concept of hiding unnecessary details and complexity from the user, while still providing the necessary functionality. This can make the code easier to use and maintain, as well as improve performance.

Abstraction is a core principle of object-oriented programming (OOP) that refers to the ability to hide the implementation details of a class from the outside world and expose only the relevant features and behaviours through a simplified interface. In C#, abstraction is achieved using abstract classes and interfaces.

An abstract class is a class that cannot be instantiated directly and can only be used as a base class for other classes. It may contain abstract methods, which are declared but not implemented in the abstract class. The subclasses of an abstract class must implement all its abstract methods to be instantiated.

Here’s an example of an abstract class in C#:

public abstract class Shape

{

    public abstract float GetArea();

}

In this example, the Shape class is declared as abstract, which means that it cannot be instantiated directly. It contains an abstract GetArea method, which is declared but not implemented in the abstract class.

Subclasses of the Shape class must provide their own implementation of the GetArea method in order to be instantiated. Here’s an example of a Rectangle class that extends the Shape class and implements the GetArea method:

public class Rectangle : Shape

{

    public float Width { get; set; }

    public float Height { get; set; }

    public override float GetArea()

    {

        return Width * Height;

    }

}

In this example, the Rectangle class extends the Shape class and provides its own implementation of the GetArea method, which calculates the area of a rectangle based on its width and height.

An interface is a contract that specifies a set of methods and properties that a class must implement. It does not contain any implementation code, but rather defines a set of public members that must be implemented by any class that implements the interface.

Here’s an example of an interface in C#:

public interface IPlayable

{

    void Play();

    void Pause();

    void Stop();

}

In this example, the IPlayable interface defines three methods (Play, Pause, and Stop) that must be implemented by any class that implements the interface.

Classes that implement the IPlayable interface must provide their own implementation of these three methods. Here’s an example of a MediaPlayer class that implements the IPlayable interface:

public class MediaPlayer : IPlayable

{

    public void Play()

    {

        Console.WriteLine(“Playing…”);

    }

    public void Pause()

    {

        Console.WriteLine(“Paused.”);

    }

    public void Stop()

    {

        Console.WriteLine(“Stopped.”);

    }

}

In this example, the MediaPlayer class implements the IPlayable interface and provides its own implementation of the Play, Pause, and Stop methods. Any class that implements the IPlayable interface can be used interchangeably with the MediaPlayer class in any context that requires an IPlayable object.

By using abstraction in this way, we can create classes that are more flexible, modular, and easier to maintain over time. We can also create a hierarchy of related classes and interfaces that define a set of common behaviours and features that can be reused and extended in different contexts.

Differences between ASP.NET Core and ASP.NET Framework

ASP.NET Core and ASP.NET Framework are both web application frameworks developed by Microsoft, but there are some significant differences between the two. Here are some of the key differences between ASP.NET Core and ASP.NET Framework:

• Open-source and community-driven: ASP.NET Core is open-source and community-driven, with contributions from developers around the world. ASP.NET Framework is also open-source, but Microsoft is the primary contributor.
• Cross-platform support: ASP.NET Core is designed to be cross-platform and can run on Windows, macOS, and Linux. ASP.NET Framework, on the other hand, is designed to run only on Windows.

• Modular design: ASP.NET Core has a modular design, with a lightweight and customizable architecture that allows developers to choose only the components they need. ASP.NET Framework has a monolithic design and includes a large set of pre-built components, which can result in larger and slower applications.

• Performance: ASP.NET Core is optimized for performance and can handle a larger number of requests per second than ASP.NET Framework. This is due to its lightweight design, which reduces overhead and allows it to run more efficiently.

• Dependency Injection: ASP.NET Core includes built-in support for Dependency Injection, which makes it easier to manage dependencies and improve code maintainability. ASP.NET Framework does not include built-in support for Dependency Injection, although it is possible to implement it using third-party libraries.

• Target platforms: ASP.NET Core is designed to target multiple platforms, including cloud, mobile, and desktop, while ASP.NET Framework is primarily targeted at web applications.

In summary, ASP.NET Core and ASP.NET Framework are both powerful web application frameworks, but they have some significant differences in terms of cross-platform support, open-source and community-driven development, modular design, performance, and target platforms. The choice between the two depends on the requirements of the project and the preferences of the developer.

Differences between ASP.NET Web Forms and ASP.NET MVC

ASP.NET Web Forms and ASP.NET MVC are two popular frameworks for building web applications in ASP.NET. Although both are built on the same platform and provide similar functionality, they have some key differences that set them apart. Here are some of the main differences between ASP.NET Web Forms and ASP.NET MVC:

• Separation of Concerns: ASP.NET Web Forms allows mixing of markup (HTML) and code (C# or VB.NET) in the same file, which can make it difficult to maintain the code. ASP.NET MVC separates the markup and code into different files, which makes it easier to maintain the code.
• Architecture: ASP.NET Web Forms uses a Page Controller architecture, where a single page contains all the code to handle the request and response. ASP.NET MVC, on the other hand, uses a Front Controller architecture, where a controller handles all the requests and responses for a group of pages.

• Testability: ASP.NET MVC is more testable than ASP.NET Web Forms, as it separates the code and markup, making it easier to write automated tests.

• URL Routing: ASP.NET Web Forms does not have built-in URL routing support, which can make it difficult to create search engine friendly URLs. ASP.NET MVC has built-in support for URL routing, which makes it easier to create clean and search engine friendly URLs.

• View State: ASP.NET Web Forms uses View State to maintain the state of controls on the page. This can result in large amounts of data being sent back and forth between the server and client, which can impact the performance of the application. ASP.NET MVC does not use View State, which can improve the performance of the application.

In summary, both ASP.NET Web Forms and ASP.NET MVC are powerful frameworks for building web applications in ASP.NET. The choice between them depends on the requirements of the project and the preferences of the developer. If you need more control over the markup and want to create search engine friendly URLs, ASP.NET MVC may be the better choice. If you need a rapid application development tool and are comfortable with the Page Controller architecture, then ASP.NET Web Forms may be the better choice.

Stored Procedure – SQL

Stored Procedure:

A stored procedure is a collection of Structured Query Language (SQL) statements with a unique name that are stored as a group in a relational database management system (RDBMS) to be reused and shared by multiple programmes.

Stored procedures can access or modify data in a database, but they are not tied to a specific database or object, which provides several benefits.

So, if you have a SQL query that you write repeatedly, save it as a stored procedure and simply call it to execute it.

Additionally, you can send parameters to a stored procedure, allowing it to take action based on the value(s) of the passed parameters.

 

Advantages of Using Stored Procedures:

An essential layer of protection is added by a stored procedure between the user interface and the database. Because end users can add or modify data but not develop procedures, it enables security through data access controls. Since data is entered consistently while using a stored procedure, data integrity is maintained. Because statements in a stored method just need to be written once, productivity is increased.

Stored procedures are preferable to embedding queries in a graphical user interface (GUI). When a problem arises in an application, it is easier to troubleshoot because stored procedures are modular. Stored procedures are also tuneable, so there is no need to change the GUI source code to improve its performance. It is simpler to code stored procedures than it is to build a query using a GUI.

When using stored procedures, network traffic between clients and servers can be reduced Because commands are performed as a single batch of code. This implies that only the call to run the procedure—rather than each individual line of code—is delivered across a network.

 

Stored Procedure in SQL Server:

SQL Server stored procedures can accept input parameters and return multiple values of output parameters; stored procedures in SQL Server programme statements to perform database operations and return a status value to a calling procedure or batch.

Except when a read-only (resource database) is utilised, user-defined procedures can be created in user-defined databases or in all system databases. They are created using Microsoft’s T-SQL or Transact-SQL. There are two sorts of temporary procedures: local and global, both of which are kept in Temporary database. While global procedures are visible to any user once they are generated, local procedures are only available to the user connection that is active at the time. Physically, system procedures are kept in a hidden resource database that comes with SQL Server. They can be found in a user-defined database as well as each system’s SYS schema.

 

Stored Procedure Syntax in SQL:

Syntax To Create Stored Procedure:

CREATE PROCEDURE Procedurename
AS
SQL STATEMENT
GO;

Syntax To Execute Stored Procedure:

EXEC Procedurename;

 

Various types of stored procedures Server SQL:

 

System Defined Stored Procedure: SQL Server already has these stored procedures defined. These are physically stored in a hidden SQL Server Resource Database and logically appear in each user-defined and system-defined database’s sys schema. The sp_ prefix is used to begin this procedure. As a result, we avoid using this prefix when naming user-defined procedures.

Extended Procedure: Extended procedures interface with external programmes to perform various maintenance tasks. These extended procedures are stored in the Master database and begin with the xp_ prefix. Essentially, these are used to automatically call programmes on the server from a stored procedure or a trigger run by the server.

User-Defined Stored Procedure: The user creates these procedures for his or her own actions. Except for the Resource database, these can be created in any system database or in a user-defined database.

CLR Stored Procedure: CLR stored procedures are a type of procedure that is based on the.net framework’s CLR (Common Language Runtime). CLR procedure integration was introduced with SQL Server 2008, allowing procedures to be coded in.NET languages such as C#, Visual Basic, and F#. I’ll go over the CLR stored procedure later.

Subquery in SQL

Query: A query is a request for data or information from one or more tables of a database.

Sub Query: In SQL language, we can place a Query inside another Query. This Query which is placed inside another query is called as subquery, also known as Nested Query

Subqueries can be used with SELECT, UPDATE, INSERT, DELETE statements along with the equality operator or comparison operator such as =, >, =, <= and Like operator.

Subquery must be enclosed in parentheses.

An ORDER BY command cannot be used in a subquery, but the main query can use an ORDER BY. The GROUP BY command can be used instead of ORDER BY in a subquery.

 

Subquery – SELECT Statement

Consider a Query

Select * from StudentDetails

When this query when executed, selects all rows of the table

Now consider an example with subquery Select

Select * from StudentDetails

where ID in (Select ID from StudentDetails where Percentage > 90);

When this set of queries gets executed,

Always the subquery gets executed first, selects the ID from StudentDetails table whose percentage is greater than 90, And then the outer query gets executed later, selecting the ID equal to the result of subquey

 

Subquery – INSERT Statement

Now consider an example with subquery Insert

Insert into StudentDetails_new

Select * from StudentDetails where ID in (Select ID from StudentDetails );

Here a new table with StudentDetails_new is created with the same structure as StudentDetails table, now to copy the datas of StudentDetails table to StudentDetails_new table , insert  statement can be used.

 

Subquery – UPDATE Statement

Now consider an example with subquery update

update StudentDetails

Set mark = mark + 5

Where mark in (Select mark from StudentDetails where mark >= 91);

Here in the table StudentDetails, the mark can be updated with a bonus of 5 marks for those who have scored mark of 91 and above using this update statement.

 

Subquery – DELETE Statement

Now consider an example with subquery delete

Delete from StudentDetails

Where mark in (Select mark from StudentDetails where mark < 50);

Here in the table StudentDetails, the datas with marks less than 50 can be removed using delete statement.

 

SQL Constraints

SQL Constraints

Constraints are the rules that can be applied on the type of data in a table. i.e, it can be used to limit the type of data that can go into a table.

Constraints can be used either when the table is created, or after the table is created.

It can be either applied to a column in a table or to the whole table.

The constraints used in SQL are:

• NOT NULL
• UNIQUE
• PRIMARY KEY
• FOREIGN KEY
• CHECK
• DEFAULT
• CREATE INDEX

 

NOT NULL: if this constraint is used in any column, then it will not allow NULL values in that particular column anymore.

Eg:

CREATE TABLE StudentDetail (

    ID int NOT NULL,

    Name varchar(250) NOT NULL,

    Branch varchar(250) NOT NULL

);

In this command, all the columns are specified with NULL Constraint, so all the columns will allow NULL data in it.

 

UNIQUE: if this constraint is used in any column, then it does not allow to repeat any data or value inn that particular column anymore.

Eg:

CREATE TABLE StudentDetail (

    ID int NOT NULL UNIQUE,

    Name varchar(250) NOT NULL,

    Branch varchar(250) NOT NULL

);

In this command, all the ID column is specified with UNIQUE Constraint, so that the ID cannot be repeated with same data.

 

PRIMARY KEY: This constraint uniquely identifies each record in a table or column and also does  not allow NULL data in  it.

Eg:

CREATE TABLE StudentDetail (

    ID int,

    Name varchar(250) ,

    Branch varchar(250),

PRIMARY KEY (ID)

);

In this command, the PRIMARY KEY Constraint is specified for ID, so that the ID cannot be repeated with same data, also ID cannot be NULL data.

 

FOREIGN KEY: The FOREIGN KEY Constraint references a row in another table, here, the table with the foreign key Constraint is called as the child table, and the table with the primary key is called the parent table.

Eg:

Parent Table::

CREATE TABLE StudentDetail (

    ID int,

    Name varchar(250) ,

    Branch varchar(250),

PRIMARY KEY (ID)

);

Child Table::

CREATE TABLE Marks (

    Mark int NOT NULL,

    Subcode int NOT NULL,

    ID int,

    PRIMARY KEY (Mark),

    FOREIGN KEY (ID) REFERENCES StudentDetail(ID)

);

Here the “Mark” of a student in the “Table Marks” refers to the “ID”  of the student in the “Table StudentDetail”.

 

CHECK: The CHECK Constraint validates condition for new value.

Eg:

CREATE TABLE StudentDetail (

    ID int NOT NULL,

    Name varchar(250) NOT NULL,

    Branch varchar(250) NOT NULL,

CHECK (Branch=’CSE’)

);

In this command, the CHECK Constraints, allows only the CSE as Branch.

 

DEFAULT: This Constraint is used to set a default value for any particular column, if any value is not specified.

Eg:

CREATE TABLE StudentDetail (

    ID int NOT NULL,

    Name varchar(250) NOT NULL,

    Branch varchar(250) DEFAULT ‘CSE’,

);

In this command, the DEFAULT Constraints, fills the Branch as CSE in default when Branch is not specified.

 

CREATE INDEX: This Constraint is used to speed-up the process, i.e it can create and retrieve any data from the database more quickly.

Eg:

CREATE TABLE StudentDetail (

    ID int NOT NULL,

    Name varchar(250) NOT NULL,

    Branch varchar(250) NOT NULL

);

CREATE INDEX ix_Branch

ON StudentDetail (Branch);

Here, in the table StudentDetail, the CREATE INDEX command creates an index ix_Branch using the Branch column.
