What are the differences between eager loading and lazy loading?

What are the differences between eager loading and lazy loading?

Eager loading loads all related data at once, while lazy loading loads data only when needed. Would you like more details?

Can you give me an example of when to use each?

Sure! Use eager loading when you know you'll need all related data upfront, like displaying a list of products with their categories. Use lazy loading for large datasets where you only need a few items at a time.

What are the performance implications of each?

Eager loading can improve performance by reducing the number of database calls, but it may use more memory. Lazy loading saves memory but can lead to multiple database calls, which might slow down performance if not managed well.

Are there any frameworks that support these loading strategies?

Yes, many frameworks like Entity Framework for .NET and Hibernate for Java support both eager and lazy loading. They allow you to choose the strategy based on your needs.
