Project Architecture

The project file structure is organized into directories:

• Controller handles incoming HTTP requests
• Service contains the business logic
• DAO implements CRUD operations for data persistence
• Model creates objects representing persisted data
• Util contains database connectivity methods common to DAO objects

The MVC architecture maps onto the directories as follows:

• Model => DAO, Model
• View => Controller
• Controller => Controller, Service

Note: Since there are only JSON HTTP responses, the view is within the Controller classes.
