Which relationship type allows for links between many records across multiple tables?

The many-to-many relationship type is characterized by the ability to link multiple records across different tables, which is essential in relational database design. In this relationship, each record in one table can be associated with multiple records in another table and vice versa. This is typically implemented through a junction table, which holds the foreign keys from both tables, thereby facilitating the connections between them.

For example, consider a scenario where you have a "Students" table and a "Courses" table: each student can enroll in multiple courses, and each course can have multiple students. This necessitates a many-to-many relationship to accurately represent these connections without redundancy in the data structure.

This capability is crucial in environments where complex interrelations between entities exist, allowing easy querying and manipulation of related records across multiple contexts. Such flexibility makes it the ideal choice for managing intricate datasets within ServiceNow and other relational databases.
