Relation or Pointer?

Question

If I have a class titled Article, and I want to add an Author column (which is class type User), should I use relation or pointer? There can only be one Author, but that Author can write many articles. I'm assuming pointer, but just making sure.

Thanks!

Answer 1

A general rule of thumb is to use a pointer for one-to-one or one-to-many relationship. Use a relation when you have a many-to-many relationship. I would say in your case it sounds like you want to use a pointer type. This guide is useful.
