In a Database Management System (DBMS), a "functional dependency" refers to a relationship between attributes in a table where the value of one attribute (called the determinant) uniquely determines the value of another attribute (called the dependent), essentially meaning that knowing the value of one attribute allows you to find the value of another attribute within the same record; it's a key concept used to ensure data consistency and quality within a database design.
