Objects and Properties

Activity‑related objects are entered through the AHD, ADD, and PAD tools. Using the Add command in the AHD, you add function definitions, process definitions, and activity usages. Using the same command in the ADD, you can also add external objects and external events.

The following list is a definition of related terms.

• Dependencies—When you join one activity to another, you create a dependency and an atomic dependency. When joining a dependency to an activity, you create a mutually exclusive control construct, a parallel control construct, or a closure control construct, and one or more atomic dependencies.
• Usages—When you join an external object or external event to a process, you create a usage of the external object or event, an atomic dependency, and a dependency.
• Data Flows—When you detail a dependency between an activity and an external object and you associate it with a data view, you add an external data flow.
• Action Diagram Statements and References to Views—When adding a statement in the action diagram, you add an object for that statement (CREATE, READ, SET, and so forth) and create references to existing entity views or attribute views.
