BizTalk Server - Business Rules Framework

 

Posted by Rickie, http://rickie.cnblogs.com

The business rules framework is a rules execution engine that allows you to create business policies that you can develop, deploy, and dynamically execute quickly without bringing your BizTalk process down. The business rules framework consists of policies, rules, vocabularies, and facts.

 

In this walkthrough, you will create a policy named ProcessApplicantPolicy with one rule named RejectRule.

 

1. Build a schema named NewHire.xsd in your local computer.

2. Click Start, point to Programs, point to Microsoft BizTalk Server 2006, and then click Business Rule Composer.

3. In the Policy Explorer window, right-click Policies, and then select Add New Policy.

4. Enter a new name, ProcessApplicantPolicy and press <ENTER>.

 

5. Right-click Version 1.0, and then select “Add New Rule” in the context menu. Enter the “RejectRule” as the rule name.

6. In the Facts Explorer window, switch to the XML Schemas tab. Then right-click Schemas, click Browse… menu item, and select the above “NewHire.xsd” file.

7. In the IF pane, right-click Conditions, and select Predicates, and then select LessThan, just like the following image.

8. Drag Age from Facts Explorer window and drop it on to argument1 in IF pane. Then In the Facts Explorer window, switch to the Vocabularies tab.

 

Add a new vocabulary named AgeValidation, and add a Minimum Age constant. Enter MinimumAge for the definition name field.

On the argument2 entry in the IF section, dray and drop the custom vocabulary parameter MinimumAge you created in the above step.

9. Drag Role (XML Schemas) from Facts Explorer window and drop it on to Then pane.

The rule is complete at this point. Save the rule. You can now test the rule/policy.
