ASP.NET Overview

ASP.NET CORE:-

The ASP.NET Core is a brand new cross-platform, high-performance, light-weight, open-source Framework which is used for developing modern, Internet-connected, cloud-based Web Applications, IoT, and Web APIs which can be developed and run on Windows, Linux, or Mac operating systems.

ASP.NET Core Framework is completely rewritten of existing ASP.NET 4.x, with architectural changes which make it more modular, scalable, open-source, high-performance, light-weight, and a cross-platform web framework. 

 ASP.NET Core benefits and features:

Nowadays, the ASP.NET Core the framework becomes more and more popular among the developers for several reasons. Let us discuss the benefits and features provided by this framework in detail.

·    Open Source:-The ASP.NET Core framework is Open Source. The Source Code of this Framework is available at https://github.com/aspnet and you are free to download the source code and even if you want then modify and compile your own version of it.

·        Cross-Platform:- The ASP.NET Core Framework is designed from scratch to keep in mind to be Cross-Platform for both development and deployment. Let us discuss what Cross-Platform is from ASP.NET Core point of view by comparing it with the earlier versions of the ASP.NET Framework.

The earlier versions of ASP.NET Framework applications can only run on windows platforms whereas the ASP.NET Core applications can develop and run on different platforms such as Windows, Mac, or Linux operating systems. We can host the earlier ASP.NET Framework 4.x applications only on IIS whereas we can host the ASP.NET Core applications on IIS, Nginx, Docker, Apache, or even self-host deployment.

To develop ASP.NET Core applications, you have multiple options like you can use either Visual Studio or Visual Studio Code. If you want then you can also use any third-party editors as per your choice.

  Full Control over HTML and HTTP Requests:- In ASP.NET Core MVC Framework, you will get full control over HTML. That means you will be able to create simple to complex type HTML pages styled with CSS and display them on the browser.

Similarly, you will also get full control over HTTP requests passed between the browser and the server. It is very easy to create an AJAX request.

In ASP.NET Core MVC, You can easily plugin and use the client-side libraries like jQuery, Bootstrap, React, and Angular.

·   Unified MVC and Web API Framework:- The ASP.NET Core provides a unified programming model for developing both Web apps and Web APIs. That means a single controller class can be used to handle both. The Controller we create in ASP.NET Core (either Web APPs or Web APIs) application is going to inherit from the Controller base class and returns the IActionResult interface. The IActionResult interface provides several implementations. The built-in result types such as the JsonResult and the ViewResult and (like this there are so many result types available that we will discuss later) implement the IActionResult interface.

In the ASP.NET Core Web API application, the controller action method is going to return JsonResult. At the same time if it is ASP.NET Core Web application, then the return type of the controller action method is going to be ViewResult. 

·    Extensible Framework:- The ASP.NET Core MVC Framework is designed to be highly extensible. That means you can create an application today, that can be extended to any levels in the future. 

Dependency Injection:- One of the most important used design patterns in the real-time application is  Dependency Injection Design Pattern. And more importantly, the ASP.NET Core framework provides the inbuilt support for dependency injection design pattern.

Testing made Maintainability:- You can easily test and maintain the applications developed using the ASP.NET Core MVC framework. This is possible because it allows you to separate different parts of your application into independent pieces and it also allows you to test them independently. The Testing frameworks such as xUnit and MOQ can be easily integrated into ASP.NET Core MVC application for simulating any scenario.

·        Handling Request and Response Pipeline:- We can handle the request and response in the ASP.NET Core application by using the new  Middleware Components. In earlier ASP.NET 4.x we generally use Handlers and Modules to handle the Request and Response pipeline. The ASP.NET Core Framework provides a lot of built-in Middleware Components and we can use those Middleware Components to handle the request and response pipeline. If you want then also you can create your own middleware components and use it in the request-response pipeline.

SQL AND ,OR, NOT Operators

Image
SQL AND, OR, NOT  OPERATOR:-  The WHERE clause can be combined with AND, OR, NOT Operators. These operators are used to filter records based on more than one condition. SQL AND OPERATOR:- The AND operator displays a record if all the conditions separated by AND are TRUE. SYNTAX:- SELECT column1 ,column2, ... FROM table_name WHERE condition1 AND condition2 AND condition3 ... ; EXAMPLE:- Consider the CUSTOMERS table having the following records:- AND Example:- The following SQL statement selects all fields from "CUSTOMERS" where Address is "Delhi" AND Age is "23 ":-  SELECT CustomerID , Name ,Address , Age ,Salary   FROM CUSTOMERS  WHERE Address = 'Delhi' AND Age = 23 ; OUTPUT:- SQL OR OPERATOR:- The SQL OR Operator is used to create a SQL statement where records are returned when any one of the conditions met. Syntax:- SELECT column1 ,column2, ... FROM table_name WHERE condition1 OR condition2 OR condition3 ... ; EXAMPLE:- The followin...

SQL Joins

SQL JOINS:-  JOIN means to combine something. In case of SQL join clause is used to combine rows from two or more table, based on a related column between them. IMPORTANCE OF JOIN:- If you want to combine two or more table the SQL JOIN is used. If you want to access more than one table through a SELECT statement. The joining of two or more tables is based on common filed between them. TYPES OF JOIN:- INNER JOIN:- INNER JOIN returns records that have matching values in both the table. LEFT(OUTER) JOIN:- This join returns all records from the left table , and the matched record from the right table. RIGHT(OUTER) JOIN:- This join returns all records from the right table, and the matched records from the left table. FULL(OUTER) JOIN:- This join returns all records when there is s match in either left or the right table.
