Salesforce Platform Developer Practice Exam

In the Model-View-Controller paradigm, which represents the model in Force.com?

1. Visualforce Pages

2. Standard and Custom Objects

3. Apex Code

4. Controllers

The correct answer is: Standard and Custom Objects

In the Model-View-Controller (MVC) paradigm applied to the Force.com platform, the model is represented by standard and custom objects. These objects define the data structure and business logic of the application, storing relevant information that the application operates on. In Force.com, standard objects like Accounts, Contacts, and Opportunities represent predefined data sets provided by Salesforce, while custom objects allow developers to create specific data structures needed for their applications. These objects include fields, relationships, and validation rules, playing a crucial role in how data is handled, managed, and interacted with within the application. Understanding the distinction between the roles of model, view, and controller is essential for effectively developing applications on the Salesforce platform. The model (objects) holds data, whereas the view (Visualforce pages) presents the data to the user, and the controller (Apex code or the controllers in Visualforce) manages the interaction between the model and the view. This clear separation of concerns helps in organizing code and maintaining modularity within the application, leading to better development practices and easier maintenance.
