P(t) = known as Predicate and these are the conditions that are used to fetch t. Thus, it generates set of all tuples t, such that Predicate P(t) is true for t. P(t) may have various conditions logically combined with OR (∨), AND (∧), NOT(¬). It will choose the tuples with vary of values or tuples for certain attribute values etc. They accept relations as their input and yield relations as their output. A tuple is a single element of relation.In database term, it is a row. Tuple Calculus provides only the description of the query but it does not provide the methods to solve it. The relational calculus in DBMS uses specific terms such as tuple and domain to describe the queries. » DS Relational Calculus is a non-procedural query language which focusses on what to retrieve rather than how to retrieve. 1.
