Implementing many-to-many relationships with foreign keys is not a step in implementing an REA diagram in a relational database. This is because in a relational database, many-to-many relationships are implemented through a third table, known as a junction table or a bridge table, which contains foreign keys to the related tables. The other options, creating tables for entities, assigning attributes to tables and identifying primary keys, and implementing one-to-many relationships with foreign keys, are important steps in implementing an REA diagram in a relational database.
