2.2 Introduction to ASP.NET

2.3 MVC Model

2.4 Analyze topics with UML

2.4.1 General USE CASE diagram

2.4.2 Squece Diagram

2.4.3 Details USE CASE diagram

2.1 Introduction to NET Framework

The NET Framework is software made by Microsoft to help build and run NET applications It creates a special environment for developers to focus on building applications without worrying too much about managing memory, system resources, and execution flow

It includes many big libraries and a runtime environment, supporting languages like C#, Visual Basic NET, and F# It offers features like generics, LINQ (Language Integrated Query), async programming support, and many others to enhance application performance and development capabilities

2.2 Introduction to ASP.NET

ASP.NET is web technology from Microsoft, making it easier to build web

applications ASP.NET includes frameworks like Web Forms, ASP.NET MVC (Model-View-Controller), ASP.NET Web Pages, ASP.NET Core (.NET), and Blazor The frameworks in ASP.NET serve different purposes and are chosen based on specific project requirements For example, Web Forms is a traditional framework for web application development, while ASP.NET MVC uses the MVC model to separatebusiness logic, user interface, and control, making development and maintenance easier

Views: They contain the user interface logic of the application Views represent the part of the interface that users interact with and are often displayed as HTML Controllers: They contain control logic and handle user requests Controllers receive HTTP requests from users, interact with Models to retrieve and update data, and directusers to corresponding Views

The MVC model makes it easier to develop and maintain applications by separating business logic, user interface, and control into separate components It also encouragesdevelopment based on Test-Driven Development (TDD), with the ability to test each part of the application independently
