What are some effective data fetching strategies for ORM?

There are several strategies for fetching data in ORM, such as eager loading, lazy loading, and batch fetching. Would you like to know more about any specific strategy?

Can you explain eager loading and when to use it?

Eager loading retrieves related entities as part of the initial query, reducing the number of database calls. It's useful when you know you'll need related data.

What about lazy loading? How does it differ from eager loading?

Lazy loading fetches related entities only when they are accessed, which can save resources but may lead to multiple queries if not managed properly.

Are there any performance considerations I should keep in mind?

Yes, using eager loading can improve performance by reducing the number of queries, but it can also increase the amount of data retrieved. It's important to balance the two based on your application's needs.
