Don’t underestimate the model in MVC

The Model-View-Controller (MVC) architecture is a widely-used pattern in software development, especially for web and mobile applications, that divides an application into three interconnected components: Model, View, and Controller. While the Model is often underutilized, it should not only represent the data structure but also encapsulate business logic such as validation rules and data manipulation methods. The text emphasizes that placing this logic within the Model rather than the Controller leads to more efficient and maintainable applications by keeping controllers lean and focused on linking models to views. Using the example of the Sails framework, it demonstrates how to define validation rules and data logic within the Model to maximize its potential, a practice applicable across various MVC frameworks. The Model's proper utilization ensures a clean separation of concerns, enhancing the application's scalability and maintainability.
