8.6 Summary of Business Layer Elements

Content: A business actor may be assigned to one or more business roles. It can then perform the behavior to which these business roles are assigned. A business actor can be aggregated in a location. The name of a business actor should preferably be a noun. Business actors may be specific individuals or organizations; e.g., “John Smith” or “ABC Corporation”, or they may be generic; e.g., “customer” or “supplier”. Figure 54: Business Actor Notation
