Repository Entries for an Activity Diagram. presents a series of actions or flow of control in a system similar to a flowchart or a data flow diagram State machines have many other features, which are described in Chapter 11 , including support for multiple regions to describe concurrent behaviors and additional transition semantics. An object diagram can be paraphrased in a natural language. You will also learn how to determine the duration of the project, and the critical path. The flow of control is triggered by the completion of actions (or activities) within the system.The flow may be sequential, concurrent, or branched, indicated by shapes such as swimlanes, forks, and joins.

Initial script for introducing object diagrams: State machine diagram shows how state of some object or system could change, so transitions on the diagram are from one state to another state. State machine diagram is a behavior diagram which shows discrete behavior of a part of designed system through finite state transitions. A state diagram is used to represent the condition of the system or part of the system at finite instances of time. • Because appointments are often made so far in advance, the receptionist usually mails a reminder postcard to each patient two weeks before their appointment.
