Functionalities of the Data Access Object(DAO) Design Pattern
Let’s see how DOA pattern allows for effective and consistent interaction with a database while abstracting away the underlying complexities
- The DAO pattern abstracts and encapsulates the details of how data is saved, retrieved, updated, or deleted in a database. This abstraction shields the rest of the application from the specific database implementation.
- It centralizes all database-related code within dedicated DAO classes. This means that the rest of the application doesn’t need to scatter database operations throughout its codebase; instead, it interacts with DAO methods.
- The DAO pattern promotes code reusability by providing a set of generic methods that can be applied to different entities. As a result, you can use similar database access patterns across various parts of your application.
Data Access Object(DAO) Design Pattern
Data Access Object Pattern or DAO pattern is a way of organizing code to handle the communication between your program and a database. It helps keep your code clean and separates the logic for interacting with data from the rest of your application.
