What is the difference between eager loading and lazy loading?

What is the difference between eager loading and lazy loading?

Eager loading loads all related data at once, while lazy loading loads data only when it's needed.

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

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

What are the performance implications of each?

Eager loading can lead to faster initial load times but may consume more memory. Lazy loading can improve performance by reducing initial load time but may introduce delays when accessing data.

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.
