Canonical Cover in DBMS

A canonical cover in database management systems (DBMS) simplifies a set of functional dependencies while preserving the same closure. It reduces the number of dependencies, eliminates extraneous attributes, and minimizes the overall dependency set. This process ensures that updates to the database do not violate functional dependencies. By creating a canonical cover, the system improves efficiency and reduces computational time. Understanding how to find and apply a canonical cover is crucial for optimizing database designs.
