A business actor represents a business entity that is capable of performing behavior.
A business actor is a business entity as opposed to a technical entity; i.e., it belongs to the Business Layer. Actors may, however, include entities outside the actual organization; e.g., customers and partners.
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.
