Use a rule specification to define the following data operations:

When you complete work on a rule specification, you can generate a metadata object called a mapplet from the rule specification. The mapplet contains the same business logic as the rule specification. An Informatica Developer user can connect the rule specification or the corresponding mapplet to a data source to verify that the data conforms to the business rule. A Developer tool user can edit a mapplet but cannot edit a rule specification.

A rule specification or mapplet applies the conditions and actions that you define to the values in each row in a data source. The rule specification or mapplet generates an output value for each row. The output specifies whether the row meets the requirements that you define for the business rule.
