One of the key objectives of an EERD is the identification of relationships among entities. In the EERD we identify the entities with rectangles and the relationships with diamonds. When converting the EERD to a relational model and the relational model to a database schema all the entities become database tables. When converting the relationships to the relational model and the database schema, it is possible that some of the relationships become discrete tables but some do not. Explain why that occurs.
