摘要
在演绎对象数据库的研究和发展过程中,仍有两个重要的问题未能很好的解决:非单调的多值结构和行为规则的继承;基于规则的行为的封装。针对前一个问题,文中提出了几种解决的方法。特别是提出了一种新的继承方法———行为继承的回退,以获得更多的信息。通过一个数据库实例以及对它的查询,进一步说明这些继承的思想。
In the process of researching and developing deductive object-oriented database,two important issues have not still been resolved properly. One is non-monotonic multiple structural and behavioral rule inheritance. The other is rule-based behavioral encapsulation. Aiming at the first one,several methods were put forward. In particular,a new inheritance method——turning back of the behavioral inheritance was put forward to obtain more information. Finally,a database instance was given and queried to illuminate more of these inheritance thoughts.
