Introduction
The Repository pattern abstracts data access, acting as a middle layer between business logic and the database.
Real-Life Example
A librarian managing a library: Instead of searching through the entire library yourself, you ask the librarian (repository) to fetch the book you need, ensuring structured access to information.
Pros
Decouples business logic from data access.
Simplifies unit testing by mocking data sources.
Centralizes queries for better maintainability.
Cons
Adds an extra abstraction layer that may be unnecessary for simple applications.
Can lead to redundant logic if not properly designed.
When to Use It
When working with databases where direct access would create tight coupling.
When centralizing business logic around data retrieval is beneficial.
Avoid for small projects where simpler data access suffices.
Conclusion
Repository is excellent for scalable applications but should be implemented only when abstraction is truly needed.
