Description: The Data Access Object (DAO) is a design pattern that provides an abstract interface to a database or other persistence mechanism. Its main goal is to separate business logic from data access logic, allowing developers to interact with the database without needing to know the details of its implementation. This pattern facilitates data persistence management by encapsulating database access operations such as create, read, update, and delete (CRUD). Additionally, using DAOs promotes code reuse and improves software maintainability, as any changes in how data is accessed can be made in one place. In various programming languages, DAOs are commonly used in applications that require constant interaction with databases, allowing the code to be cleaner and more organized. This pattern is particularly relevant in software architectures that follow object-oriented design principles, where separation of concerns is essential for developing scalable and robust applications.
