RELATIONAL CONDITION:

 We know that a relational condition specifies a comparison between two operands and has the form.

    Operand-1    relational-operator   operand-2

where the relational-operator can be anyone of the shown below:

    IS    [NOT]     GREATER     THAN

    IS    [NOT]              >            THAN

    IS    [NOT]     LESS              THAN

    IS    [NOT]              <            THAN

    IS    [NOT]     EQUAL           TO

    IS    [NOT]              =              

It was acknowledged earlier that the operands can be an identifier or a literal. Though, either operand can also be an arithmetic expression but should contain at least one reference to an identifier. Occasionally, operand-1 and operand-2 are respectively referred to as the subject and object of the relational condition.
