The lines between entities within an Entity-Relationship Diagram [ERD] represent an interdependency between the involved entities. In a normalized designed, this interdependency is both semantic and functional, as in, "a HOUSE has one-or-more DOORs," "an ORDER has one-or-more ORDER LINEs," or "a STUDENT enrolls in zero-to-many CLASSes."
