企业内部的很多业务都可以抽象为一个或者若干个工作流，最典型的是收发文工作流。一个发文流程可能要经历起草，审批，校对，领导签字，传阅等步骤。传统的办公模式完成此流程需要投入很多人力，而且运转起来较慢，容易出错，如果采用办公自动化系统，公文的流转就可以自动化，显然有很多好处。

UML（Unified Modeling Language)是一种面向对象的建模语言，它已经广泛用于面向对象系统的分析和设计。统一过程(Unified Process)是一种软件工程方法，它将软件开发过程分为一系列的工作流程(Workflow)，充分发挥了迭代的开发思想，是软件开发成功的重要因素。

Struts是基于JAVA的一个开源项目，采用模块化的设计思想将业务逻辑，数据存储和用户界面分离，简化了企业级应用程序的构建。

　　本文描述了葫芦岛锌厂的办公自动化系统的开发过程，依据统一过程的开发思想，利用UML构建和描述系统的结构与行为，并用Struts完成了系统的最终实现。

-enterprises within the many businesses that can be abstract or for a number of work-flow, The most typical is the text Transceivers work flow. An outgoing message flow may experience drafting, examination, proofreading, leading signature, circulation and other steps. The traditional mode of office to complete this process requires a lot of manpower and operating it slow, prone to error, If the use of office automation systems, document, the transfer can be automated, obviously has many advantages. UML (Unified Modeling Language) is an object-oriented modeling language It has been widely applied to object-oriented system analysis and design. Unified Process (Unified Process) is a software engineering approach, It will software development process is divided into a series of workflows (Workf
