Answer a few questions → Get a clear recommendation.

Options you can choose from:

CQRS - Command Query Responsibility Segregation

Separation of write (Command) and read (Query) operations. Allows read and write operations to be optimized separately. Can optionally be combined with event sourcing, but works independently too.

CRUD - Create, Read, Update, Delete

The traditional approach, where a single model handles all operations: create, read, update, and delete. Simple, fast, and easy to understand.
