ProductDAO

ProductDAO stands for Product Data Access Object. It is a design pattern that is used to abstract the database operations required to access and manipulate data related to products in an application. The ProductDAO encapsulates the logic required to interact with the database and provides a simple interface for the rest of the application to use.

The ProductDAO typically provides methods for creating, updating, deleting, and retrieving products from the database. The DAO also manages the connections to the database and handles any errors that occur during the database operations.

Using a ProductDAO can help to simplify the codebase of an application by separating the database logic from the rest of the application. This can make it easier to maintain and modify the application over time. Additionally, the ProductDAO can help to improve the performance of the application by reducing the number of database queries that need to be executed
