This chapter presented you with an overview of the Business Rules Subsystem. Specifically, you learned the purpose of this subsystem, concepts in business policy management, guidelines for identifying business rules and enterprise objects, and some advice on working with key stakeholders. You also learned about unearthing existing implementations of business rules, given the dynamic nature of organizations, large and small. Finally, you were presented with the classes and implementations in the subsystem, including a code listing. |

Q True or False: For simpler applications, the Business Rules Subsystem can be implemented with only one class residing on the client machine. For more complex applications involving a number of groups of users within an organization, business classes can reside on any number of distributed computers. |
