Which of the following correctly states an advantage AND a disadvantage of the MVC pattern?

Advantage: eliminates the need for a database; Disadvantage: cannot be used for web applications

Advantage: allows data to change independently of its representation, and supports presenting the same data in different ways; Disadvantage: can involve additional code and complexity when the data model and interactions are simple

Advantage: removes the Controller entirely in simple applications; Disadvantage: the View must always know about the database

Advantage: requires no knowledge of object-oriented programming; Disadvantage: makes it impossible to update the View without updating the Model

Correct Answer

Explanation

MVC's key advantage is separation of concerns: data (Model) can change independently of its presentation (View) and vice versa. It also supports multiple representations of the same data with changes in one representation shown in all. Its disadvantage is additional code complexity, especially when the data model and interactions are simple enough that such separation is not needed.
