Note: I'm sorry that that wasn't a good answer. Please hold on while I contact an expert.

Weegy: Many-to-Many relationships in an entity relationship diagram tend to conceal areas of poor understanding, and in fact some databases will not allow you to create such relationships. Almost always, a Many-to-Many relationship conceals a hidden entity. [ For this reason, identifying and adding the hidden entity to the model eliminates Many-to-Many relationships. This usually ends up with an extra entity being added, which then has a One-to-Many relationship with the existing entity. www.sqa.org.uk/e-learning/SDM03CD/page_37.htm ]
