What are the differences between various ORM patterns?

There are several ORM patterns, including Active Record, Data Mapper, and Unit of Work. Each has its own use cases and benefits.

Can you explain the Active Record pattern?

Sure! The Active Record pattern combines data access and business logic in a single class, making it easy to use but can lead to tight coupling.

What about the Data Mapper pattern?

The Data Mapper pattern separates the in-memory objects from the database schema, allowing for more flexibility and easier testing.

Which pattern is better for large applications?

For large applications, the Data Mapper pattern is often preferred due to its separation of concerns and better scalability.
