The event classes are stereotyped as a business event. Their relationships . generalization hierarchies can Figure Business events are modeled as classes in a class hierarchy. The receive symbol concave pentagon and the send symbol convex pentagon are used in a process diagram to illustrate receiving and sending events respectively as shown in Figure . The receive symbol can be read so that the process waits for this event to occur or in case of a decision point with several alternatives the events that will trigger each of the specified alternatives. The send symbol indicates that the process generates and sends the event between two activities. Either of the event symbols send or receive can be attached to an object with a dependency arrow which shows from which object the event is sent or received. If an event symbol is drawn to a process symbol an expansion of the process symbol shows exactly how and where in the process the event is received or sent. An event symbol can also be attached to its opposite symbol in another process . a send symbol to a receive symbol or vice versa to indicate how the processes communicate. Figure Receiving and sending business events during a process. Modularizing the Business System A large system will have many processes. To handle all the processes they must be grouped or modularized so that a modeler can concentrate on only one set of processes at a time. Processes are modularized using the UML package mechanism. Processes are allocated to a specific package sometimes referred to as a subsystem in information systems see Figure each of which contains a set of processes and their subprocesses. A package can in turn also contain other packages. Gvslpmflf flnj irg 1 L T-aiinq Figure Packaging processes together. A package can contain processes that are not directly .
