If I have a class titled <code>Article</code>, and I want to add an <code>Author</code> column (which is class type <code>User</code>), should I use relation or pointer? There can only be one <code>Author</code>, but that <code>Author</code> can write many articles. I'm assuming pointer, but just making sure. <img src="https://i.stack.imgur.com/LOpuN.png" alt="enter image description here"> Thanks!

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.
