摘要: 针对面向数据对象模型环境适应性研究较少且未获得实用研究成果的问题,对企业中的各类数据对象进行分析和抽象,遵照柔性、封装性、高效性等设计原则给出该模型的设计,并基于成熟的信息技术进行实现。通过应用实例对可扩展数据对象模型进行验证,证明该模型可以适应一定程度上企业环境的变化。

关键词: 可扩展, 数据对象, 易变性

Abstract: The adaptability of data object model to the changing enterprise environment has been considered as a key factor for the success implementation of enterprise information system. Few studies and results are related. Based on the principles of extensibility, encapsulation and efficiently, an extensible data object model is designed by analyzing and abstracting the existing various data objects in enterprise. The model is built up and implemented using mature information techniques. An application example is given to show that the proposed model is adaptive to the changed enterprise environment to some extent.

Key words: extensibility, data object, changeability
