Conclusion

  In this lesson, you learned:

• The meaning of CRUD.
• How to create, read, update, and delete data from a database.

This lesson covered CRUD operations in Room databases. CRUD is an acronym for Create, Read, Update, and Delete. CRUD represents the primary operations for interacting with database data. In Room, these operations are managed through Data Access Objects (DAOs). Best practice suggests using a repository pattern when working with databases. This pattern maintains clean architecture and manages multiple data sources seamlessly.  The repository pattern also abstracts data operations. This abstraction provides a unified way for accessing data regardless of its source, such as a network or local database. Your notes app demonstrates how to define a NotesRepository interface and its implementation. The interface leverages coroutines for efficient background processing. This approach simplifies data handling across the app and enhances testability.
