Validation rule-salesforce

Validation rule:

A validation rule is a formula, evaluated when a record is saved, that prevents the save operation if the formula evaluates to true.

Note:

·         That the validation is executed whenever a user attempts to insert or change a record.

·         Existing records are not checked to see if they pass any new validation checks.

·         Uses an error condition formula that evaluates to either true or false
