Introduction to Rule Specifications
A rule specification is an asset that represents the data requirements of a business rule in logical form. You configure a rule specification in the Design workspace of the Analyst tool. You generate one or more metadata objects called mapplets from the rule specification. Informatica developers can apply the mapplets to the business data to verify that the data conforms to the business rule.
Use a rule specification to define the following data operations:
- •Define the types of data that a business data set contains.
- •Define the set of conditions that the business data must satisfy.
- •Define the actions to take when the data satisfies the conditions of the business rule.
- •Define the actions to take when the data fails to satisfy the conditions of the business rule.
The mapplets apply the conditions and actions that you define to the values in each row of a data set. The mapplets generate an output for each row. The output specifies whether the row meets the requirements that the rule specification defines for the business rule.
