Hi all, I am trying to understand the meaning of "Direct Relationship" between two entities belonging to an ERD, i.e., an entity-relation diagram associated with a Relational database. A Google search did not return anything helpful.
Say, A,B are the entities in question. I assume this means that there should be an arrow joining them, i.e., A,B are incident with each other. Or does it mean that there is a path joining A with B?
