对象依赖集合性质的研究

在复杂对象模式的规范化设计中，对象间的语义关系起了重要作用。然而，目前还没有关系的研究报告，讨论了对象依赖集合的一些性质，首先概括了基本概念和性质；然后给出并证明获取一个OD集合所有关键字的JINGSI算法；最后证明要作为复杂对象模式规范化设计的MIMI算法输入的OD集合的特性，并基于此改进复杂对象模式规范化设计。

RESEARCH ON PROPERTIES OF A SET OF OBJECT DEPENDENCIES

In normalization design of complex object schemes, the semantic relationships among objects play an important role. But there is no research on it. Some properties of a set of object dependencies are discussed in this paper. First summarized are some basic concepts and properties about object dependency (OD), key, and reduced OD. Then, algorithm JINGSI producing all keys with respect to a set of ODs is given and proved. Finally, the properties for the set of ODs as the input for normalization design of complex object schemes are shown, and based on it normalization design for complex object schemes is improved.
