| 摘 要： | 给出了包含五个特征域的部分-整体语义模型的完整的形式化定义。部分-整体语义联系是现实世界中客观实体之间常见的联系,然而流行的商用OODBS并没有为之提供内在的支持。为此,MHalper等人提出了一种基于元类机制的将部分-整体语义联系集成到OODBS中的方法,由于只有少数的OODBS支持元类机制,故而M.Halper等人提出的方法存在一定的局限性。本文针对这一问题提出了一种新的将部分-整体语义联系集成到OODBS中的方法,该方法对于OODBS本身没有任何的限制,因此具有较广泛的通用性。

| Abstract: | The integral definition of our model is presented,in which the characteristic dimension integrity is to describe the integrity of objects,and part-whole semantic relationship is the familiar relationship between objects,but the popular commercial OODBS does not provide the built-in support for it.So,Mr. Halper presented a methodology based on the metaclass mechanism to incorporate the part-whole semantic relationship into OODBS.Because there are a few kinds of OODBS which support the metaclass mechanism,this methodology has limitation to some degree.Dealing with this problem,in this dissertation,a methodology to incorporate part-whole semantic relationship into OODBS is presented.The methodology is universal for there is no limitation of OODBS. |
