摘要
在企业信息系统实施过程中存在的结构不良问题以及低效率的分析设计方法，使企业不能在经营过程不断变化时作出快速响应，并且容易导致潜在的错误、拖期和额外的成本．文章在组件技术和分布式对象技术的基础上，提出了基于经营知识的经营对象的层次结构模型．在这一模型中，中等粒度的过程组件通过独特的数据端口映射以及内嵌规则库的控制，屏蔽了精细粒度的基本经营对象之间复杂的调用关系，并且提供了４种应用系统的重构策略．最后，文章给出了利用Ｐｅｔｒｉ网建立经营对象行为模型的实用方法．通过这一方法，可以在模型与分布式对象ｓｅｒｖｅｒ之间建立清晰的对应关系，从而使企业信息系统的快速开发和设计成为可能．
The existent ill structured architecture and the low efficiency of analysis and design methods during the implementation of enterprises information systems are the main factors, in regard to the continuous changes of the business processes, which disable the quick response capability of enterprises and are apt to result in potential errors, delays and extra costs. On the basis of the componentware and distributed object technology, a hierarchical model of knowledge based business objects is proposed in this paper, within which the medium grained process components mask the intricate interactions between fine grained basic business objects by means of the special dataports mapping and built in rulebase control. Also, four kinds of reconstruction strateqies are available under this model. Finally a kind of Petri net based approach to model the business objects' behaviors in the business processes is given. Through this approach, the unambiguous relationship between the model constructs and the distributed object servers can be explicitly established so as to facilitate the rapid development of enterprises applications.
