Question

I have an Order object and the Order object contains a Person object which stores the information about the person who placed the order. When I populate the Order object am I supposed to populate the Person object as well? Or would I be better off calling order.GetPerson() whenever I need to access to the person who placed the order.

Answer 1

You may consider the LazyLoading approach. So that the Person data will be fetched and loaded when it is required (queried for the first time)

Lazy loading is a design pattern commonly used in computer programming
to defer initialization of an object until the point at which it is
needed
