Explanation

The Data Access Object (DAO) pattern abstracts and encapsulates all access to a data source, separating data persistence logic from business logic. This creates a dedicated layer for database operations, making the code more maintainable and testable. Encapsulation, Polymorphism, and Inheritance are OOP principles, not patterns for data access separation.
