Associative entity

An associative entity is an element of the Entity-relationship model.

The database relational model does not offer direct support to many-to-many relationships, even though such relationships happen frequently in normal usage.

The solution to this problem is the creation of another table to hold the necessary information for this relationship.

This new table is called an associative entity.
