Explanation

A cardinality of 1...n to 1...n represents a many-to-many relationship where each record in one table can relate to multiple records in the other table, and vice versa. In database modeling, this typically requires a bridging table or junction table to properly implement the relationship. The 'n' notation indicates multiple possible matches on both sides.
