摘要
统一建模语言UML存在着面向对象建模的不足,例如,用多个模型表示系统,模型的一致性难以保证.UML的工作主要集中于面向对象的分析和设计阶段,在实现阶段并没有做过多的努力等等,给系统设计带来了不便.提出了在UML建模环境中引入对象过程图（object-process diagram,简称OPD）,为多个模型的一致性提供了统一的标准,提高了程序文档的可理解性和可维护性,使得扩展后的UML具备从面向对象分析到程序设计的完全可视化的描述能力.
UML is a powerful language for object-oriented modeling, but it has some explicit drawbacks. For example, it lacks a model check mechanism so it is difficult to keep the consistence of Meta Model. Moreover, the code building of UML is so scant in spite of the strong power on the OOP analysis and design steps. All of these bring lots of inconvenience in the system building. In this paper, the UML modeling environment is extended by using object-process diagram (OPD), through which people can set a uniform standard for multi-modeling and make the extended UML has the ability of both OOP analysis and design and visible program design.
