Feature rules enforce business rules by performing specific tasks on your data whenever you change an associated feature class in the database.
Feature rules are associated with particular feature classes. They enforce business rules by performing specified tasks whenever you change a feature class in the database. Feature rules help to maintain the integrity of data in the database. For example, when you update the database by moving a feature, an associated feature rule can ensure that the location of the label that describes the feature is also updated.
Feature rules are characterized by whether they are stored in the database as server-side rules, or are written in a .NET language and stored in a dynamic linked library (DLL) as client-side rules. A further classification of client-side feature rules is by component and module.
