What is the role of an associative table?

An associative table, also known as a junction table or linking table, acts as a bridge between two related tables in a relational database, particularly in many-to-many relationships. It contains foreign keys that reference the primary keys of the associated tables, enabling efficient data retrieval and organization. By using an associative table, it allows for a more normalized database structure, reducing redundancy and maintaining data integrity. Additionally, it can store attributes specific to the relationship itself, further enriching the data model.
