摘要
通过探寻面向对象数据库与知识库技术相结合的途径,研究演绎对象数据库系统实现的关键技术。以基于演绎数据库系统SD-DDBS,设计实现了一个演绎对象数据库系统原型SD-DOOD。系统支持类,类层次、对象、属性、方法、继承和封装等面向对象数据库系统的核心概念,支持演绎对象等演绎数据库的概念,提供了图形用户接口(GUI),便于用户进行创建、查询等操作。
The main tasks are to explore the means of combining the object-oriented database and the technology of knowledge base, and to study the key technologies of implementing the deductive object database system. The design and implementation of a prototype system of deductive object database, SD-DOOD are elaborated, which is based on SD-DDDB. This system supports the key concepts of object-oriented database such as class, class hierarchies, object, attribute, methods, inheritance and encapsulation etc., and the deductive database such as deductive object etc.. Besides, it provides the graphical user interface (GUI), which facilitates user's operations of creating, query and so on.
