The type of data that describes a many-to-many relationship within a database is intersection data. In databases, many-to-many relationships occur when multiple records in one table are associated with multiple records in another table. To effectively manage and represent this type of relationship, a junction table, also known as an intersection table, is used.

Intersection data typically contains foreign keys that reference the primary keys of the two tables involved in the many-to-many relationship. This structure not only allows for the representation of complex relationships between records but also facilitates effective querying and data integrity.

In contrast, transactional data pertains to records associated with transactions, such as sales or purchase records, which may or may not illustrate relationships between different entities. Ad hoc data refers to data that is created for a specific purpose and doesn't typically form part of a structured relationship across multiple tables. Hierarchical data is organized in a tree-like structure, representing one-to-many relationships, but does not apply to many-to-many relationships.
