摘要
介绍了在演绎库（ＫＢＡＳＥ－Ｐ）与对象库（ＦＯＯＤＢ）基础上实现的一个演绎的面向对象数据库系统（ＤＯＯＤ）。系统支持对象的递归查询等操作，还引入了ＩＯＤＢ与ＤＯＤＢ等概念，用于演绎对象的生成。系统采用Ｏ－ＤＡＴＡＬＯＧ语言，用于实现对象间的演绎，并继承了演绎库的优化策略。
A deductive object oriented database(DOOD) system, which is based on the former deductive database(KBASE P) and object oriented database(FOODB), is introduced in this paper. The system supports recursive query of objects, IODB and EODB as well. O DATALOG language is used to represent the deductive among objects. The optimization strategy of the deductive systems is also employed.
