DEVI - Logical and Relational Expressions - Logical and Relational Operators and Expressions

The result is always a Boolean value.
These expressions use logical or relational operators to determine their value.

Relational Operator

Used in a relational expression to test a relationship between the term preceding it and the term following it, resulting in a Boolean value.

The relational operators:

• =(equal to)
• <(less than)
• >(greater than)
• <=(less than or equal to)
• >=(greater than or equal to)
• <>(not equal to)
• IN(included in set).

Relational Expression

An expression, that by using a relational operator, compares values and results in a Boolean.
Terms of this expression are usually not Boolean themselves, but they must be compatible with each other.

Logical Operator

Uses one or two Boolean terms in a logical expression.

The logical binary operators are:

• AND
• OR
• XOR (exclusive OR).

The logical operator is:

• NOT.

Logical Expression

Uses one logical operator, which results in a Boolean value.
It can have terms of any type.
It can have multiple terms, but the terms must all be of type Boolean.
