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(¬). Like Relational Algebra, Relational Calculus does not specify the sequence of operations in which query will be evaluated. It is same as TRC, but differs by selecting the attributes rather than selecting whole tuples. In contrast to tuple relational calculus, domain relational calculus uses list of attribute to be selected from the relation based on the condition.
