The answer is True: In a relational database, a bridge table breaks a many-to-many relationship up into two one-to-many relationships.

Explanation:

  • In a relational database, a many-to-many relationship occurs when multiple records in one table are associated with multiple records in another table. This type of relationship cannot be directly implemented in a relational database.
  • To resolve this, a bridge table (also known as a junction table or associative entity) is used. This table contains foreign keys that reference the primary keys of the two tables involved in the many-to-many relationship.
  • By doing so, the bridge table effectively breaks the many-to-many relationship into two one-to-many relationships: one between the first table and the bridge table, and another between the bridge table and the second table.
  • This allows for the representation of many-to-many relationships in a way that is compatible with the relational database model.
