CORE DEFINITION

The Model-View-Controller (MVC) pattern is a software architecture pattern in software engineering that divides a software system into three basic parts: Model, View, and Controller. The MVC pattern was first proposed by Trygve Reenskaug in 1978 and was invented at Xerox PARC in the 1980s for the programming language Smalltalk. The purpose of the MVC pattern is to achieve dynamic programming, simplify subsequent modifications and extensions, and enable reuse of parts of the program. Additionally, this pattern makes the program structure more intuitive by simplifying complexity. By separating the basic parts of the software system, it also assigns appropriate functions to each part. Professionals can group based on their expertise: Model - programmers write the functions (implement algorithms, etc.), database experts handle data management and database design (can implement specific functions).

Anchor fast decisions

Reduce complexity through separation of concerns: The Model holds data and business rules, the View is responsible for presentation, and the Controller receives input and coordinates the other two. After decoupling, modifying the interface does not affect the logic, and modifying the logic does not require rewriting the interface; each can evolve and be tested independently.
