An application interaction represents a unit of collective application behavior performed by (a collaboration of) two or more application components.
An application interaction describes the collective behavior that is performed by the components that participate in an application collaboration. This may, for example, include the communication pattern between these components. An application interaction can also specify the externally visible behavior needed to realize an application service. The details of the interaction between the application components involved in an application interaction can be expressed during the detailed application design using, for example, a UML interaction diagram.
An application collaboration may be assigned to an application interaction. An application interaction may realize an application service. Application services and technology services may serve an application interaction. An application interaction may access data objects. The name of an application interaction should clearly identify a series of application behaviors; e.g., “Client profile creation” or “Update customer records”.
