A **canonical cover** (also known as a **minimal cover**) is a concept in database theory, specifically in the context of functional dependencies in relational databases. It is used to simplify a set of functional dependencies while preserving their semantic meaning. The goal of finding a canonical cover is to reduce the number of functional dependencies and the complexity of the set while keeping the original dependencies intact. ### Characteristics of a Canonical Cover: 1. **Minimality**: A canonical cover contains no redundant functional dependencies.
