The Data Access Object (DAO) architecture pattern is used to separate the persistence logic from the business logic in an application. In this pattern, the DAO acts as an intermediary between the application and the database.
The DAO provides a simple and consistent interface to the database for the application. It shields the application from the details of how the data is stored in the database and provides a high level of abstraction.
The DAO pattern typically includes methods for the application to create, read, update, and delete data from the database. These methods can be optimized for performance, security, and reliability.
The DAO pattern also makes it easier to switch between different databases or storage systems without affecting the application code. This is because the data access logic is abstracted away from the application logic and stored in the DAO.
