Tuple (t) variable range for all tuple of relation or table (R). Tuple relational calculus works on filtering the tuples based on the specified conditions.TRC is the variable range over the tuples and is a type of simple subset of the first-order logic.TRC considers tuples as equal status as variables, and field referencing can be used to select the tuple parts. The Tuple Relational Calculus list the tuples to selected from a relation, based on a certain condition provided.
