What is the difference between greedy, lazy, and explicit data loading?

Eager Loading loads related data along with the main object in a single database query.

Lazy Loading defers loading related data until it is accessed. Each access to a related collection or object may result in a separate database query.

Explicit Loading is similar to Lazy Loading but requires writing code to explicitly load related data using methods like Load() or Collection(). It does not happen automatically when accessing the property.
