In this chapter, we've covered the principles that underpin the Business Rules Engine to help you understand what happens under the covers and how you should approach the design of your rules.
We've then covered how rules can be constructed using the Rules Composer and the various fact sources that can be used when constructing your rules and how vocabularies can help when creating your rules.
We then finished up by discussing how Long-Term Fact Retrievers can significantly improve the performance of your rules policies if you make use of identical facts regularly. We also covered how the Tracking Interceptor is invaluable when using the Rules Engine.
In the next chapter, we'll cover how your BizTalk solution should be tested and a number of tools that can be used to support your testing.
