The relational calculus is a part of the relational model for databases and provides a declarative way to specify database queries. It consists of two calculi, the tuple relational calculus and the domain relational calculus. The relational calculus is similar to the relational algebra, but while the algebra is imperative, the calculus is declarative. According to Codd's theorem, the algebra and calculus are logically equivalent.
