At first glance, the three tiers may seem similar to the model-view-controller (MVC) concept; however, topologically they are different. A fundamental rule in a three tier architecture is the client tier never communicates directly with the data tier; in a three-tier model all communication must pass through the middle tier. Conceptually the three-tier architecture is linear. However, the MVC architecture is triangular: the view sends updates to the controller, the controller updates the model, and the view gets updated directly from the model.

What is the Model View Controller Design Pattern?
The Model-View-Controller architecture compartmentalizes the data and business logic (model) from the presentation (view) from the user action interpreter (controller). This pattern is the hardest on the exam. The idea is closely related to the recent move from two-tier to three-tier architectures. The 3 tiers in a MVC Architecture of a J2EE Application are: 1. Model - Usually JavaBeans 2. View - Usually JSPs 3. Controller - Usually Servlets This pattern is a clear functional separation of roles. It is a formalization of the data-business-presentation movement that dominated three-tier architectures over the last decade. This pattern is very abstract. It is not simply a front end to a datasource connection. This would be like an automobile. The speed of a car is affected by the accelerator pedal (Controller), the speed is shown by the speedometer (View), and the speed is determined by the engine power (Model).
