An alternative to relational algebra is relational calculus. It is a query system where queries are expressed as variables and formulas on these variables. It is a non-procedural or declarative by nature. In this, the formulas describe the properties of the required result relation without
describing how to compute it i.e., query represents only results and hides the procedure to find the result. Relational calculus is based on predicate calculus, which is used to symbolize logical arguments in mathematics. Relational calculus has two variants. The first one is called
Tuple Relational Calculus in which variables take on tuples as values. The second one is called Domain Relational Calculus in which variables range over the underlying domains.
Relational Calculus has strongly influenced the design of many query languages like SQL and QBE.
