We've covered a lot of ground in this chapter that can be summarized by the following key points:
Business rule in MDS are If/Then expressions that are made up of conditions and actions
The business rules are run on the following events:
Creating a member
Editing a member
Validating a version that can be carried out from the front-end using a stored procedure or using the API
Actions can change the value of member attributes, generate member values, and cause a member to be invalid
E-mail notifications are sent when a validation action is invoked
External actions can initiate a SharePoint workflow that can be used for complex approval processes
Looking ahead to the next chapter, we will cover using the Master Data Services API, and see how it can be used to create custom .Net solutions.
