Research on. NET Intelligent Platform Based on Three Layer Structure

The. NET three-tier architecture is a commonly used software development architecture that divides applications into three logical layers: the presentation layer, the business logic layer, and the data access layer. The presentation layer is responsible for interacting with users and receiving user input; The business logic layer processes business rules, validates data, and executes application logic; The data access layer is responsible for interacting with the database, including querying, updating, and deleting data. Using the. NET three tier architecture can reduce code coupling and improve application scalability and maintainability. Developers need to design the interfaces and communication methods between various layers based on the requirements of the application. They can use ASP.NET MVC or Web Forms to build Web applications, and use C # language to write business logic and database operation code.
