Both sequence diagrams and communication diagrams are kinds of interaction diagrams. An interaction diagram shows an interaction, consisting of a set of objects or roles, including the messages that may be dispatched among them. Interaction diagrams address the dynamic view of a system. A sequence diagram

序列圖和通信圖都屬於交互圖．交互圖表達的是這樣一個交互：由一組對象和角色組成。消息在它們之間傳遞．交互圖處理系統的動態視圖．序列圖作為交互圖。它更著重消息發送時的時間順序；通信圖作為交互圖。則更著重對象或角色在發送和接收消息時的組織結構．序列圖和通信圖表達的基本概念非常相似，但每一個圖註重的是不同的概念視圖：序列圖著重的是時間順序，而通信圖著重的是消息流的數據結構．時序圖(超出了本書範圍)表達的是消息交換時的實際時間．

A state diagram shows a state machine, consisting of states, transitions, events, and activities. A state diagrams shows the dynamic view of an object. They are especially important in modeling the behavior of an interface, class, or collaboration and emphasize the event-ordered behavior of an object, which is especially useful in modeling reactive systems.

狀態圖表達的是一個狀態機，由狀態，傳輸。事件和活動組成．一個狀態圖顯示對象的動態視圖．在構建接口，類或是交互的行為時它們尤其重要，它註重對象行為所發生的事件順序。這在構建反應系統時特別實用．

An activity diagram shows the structure of a process or other computation as the flow of control and data from step to step within the computation. Activity diagrams address the dynamic view of a system. They are especially important in modeling the function of a system and emphasize the flow of control among objects.

活動圖顯示過程的結構，或是其他計算，如控制流和數據計算過程．活動圖處理系統的動態視圖．在構建系統的功能時尤其重要，重點是對象間的控制流．

A deployment diagram shows the configuration of run-time processing nodes and the components that live on them. Deployment diagrams address the static deployment view of an architecture. A node typically hosts one or more artifacts.

部署圖顯示執行時處理節點的配置和節點中的活動組件．部署圖處理體系結構的靜態部署視圖．一個節點通常指包括有一個或很多其它個產品的主機．
