Implementing algorithms of inheritance character in deductive object-oriented database SD-DOOD
演绎对象数据库SD-DOOD中继承性的实现算法

The framework of deductive object-orientod database SD-DOOD system was introduced. Several inheritance methods which could be implemented in the system were presented. The algorithms of schema, instance and query relating to these methods were realized. The time complexities of these algorithms were analyzed. The experiment resuhs show that these algorithms are feasible and efficient.
