When using an REA diagram to develop a database, a many-to-many relationship must be broken into two, one-to-one relationships. The type of relationship between two entities is determined by minimum and maximum cardinalities. Which of the following is not one of the three steps to implementing an REA diagram in a relational database? Why might the same REA diagram result in different relationship cardinalities? The primary key for M:N relationship tables always consists of two attributes and is the primary key of the most important entity linked to that relationship. Many-to-many relationship tables only use foreign keys.
