   Entity-relationship diagram
   • Used to clarify table relationships in a relational
   database
   • Relational database tables may have:
   • One-to-one relationship
   • One-to-many relationship
   • Many-to-many relationship
   • Requires “join table” or intersection relation
   that links the two tables to join information
