【文章內(nèi)容簡介】 a state machine in which most or all of the states are action states or activity states, and in which most or all of the transitions are triggered by pletion of activity in the source states.? An activity graph emphasizes the sequential and concurrent steps of a putational procedure or a workflow. 用途An activity graph is a variation of a state machine in which the states represent the performanceof actions or subactivities and the transitions are triggered by the pletion of the actions orsubactivities. It represents a state machine of a procedure itself.? 描述業(yè)務(wù)模型（ Use Case分析）? 描述類動態(tài)模型（類設(shè)計）活動圖與狀態(tài)圖比較? An activity diagram is a special case of a state diagram in which all (or at least most) of the states are action or subactivity states and in which all (or at least most) of the transitions are triggered by pletion of the actions or subactivities in the source states. ? The entire activity diagram is attached (through the model) to a class, such as a use case, or to a package, or to the implementation of an operation. The purpose of this diagram is to focus on flows driven by internal processing (as opposed to external events). ? Use activity diagrams in situations where all or most of the events represent the pletion of internallygenerated actions (that is, procedural flow of control). ? Use ordinary state diagrams in situations where asynchronous events occur.Action state? An action state is a shorthand for a state with an entry action and at least one outgoing transition involving the implicit event of pleting the entry action (there may be several such transitions if they have guard conditions). ? Action states should not have internal transitions or outgoing transitions based on explicit events, use normal states for this situation. ? The normal use of an action state is to model a step in the execution of an algorithm (a procedure) or a workflow process.Activity state? A subactivity state invokes an activity graph. When a subactivity state is entered, the activity graph “nested” in it is executed as any activity graph would be. The subactivity state is not exited until the final state of the nested graph is reached, or when trigger events occur on transitions ing out of the subactivity state. ? Since states in activity graphs do not normally have trigger events, subactivity states are normally exited when their nested graph is finished. ? A single activity graph may be invoked by many subactivity states.ActionObject Flow? Actions operate by and on objects. These objects either have primary responsibility for? initiating an action, or are used or determined by the action. Actions usually specify calls sent? between the object owning the activity graph, which initiates actions, and the objects that are? the targets of the actions.舉例1）選課程計劃2）戶籍管理3）喝咖啡Component DiagramA physical, replaceable part of a system that packagesimplementation and conforms to and provides therealization of a set of interfaces.

You can draw a dependency relationship from a ponent to an interface of another ponent, which means that the client ponent uses the operations of the other ponent. You can also draw a realize relationship from a ponent to an interface of another ponent, which means that the client ponent provides the operations of the other ponent.
