Business Policy Business Policy is a container in which

business rules are defined, versioned, tested, deployed and executed.

The policy may contain one or more rules for deployment

There are three states of a business policy,EditablePublishedDeployed

Sample Application We need to create and test a simple business rule that a business process can

use. The business process needs to validate a document and receive the result.

We have an xml instance of the schema ‘NewHireList’. Here according to the Age populated in the input instance the Applicant’s Role is decided as a ‘ValidApplicant’ or an ‘InvalidApplicant’

The policy deciding the above mentioned condition is as

If Age < Minimum Age then

Role changes to INVALIDAPPLICANT

where the minimum age will be set as 18 years inside the Business Rules Composer
