摘要
介绍了演绎对象数据库SD-DOOD系统的结构,给出了系统中可以实现的继承方法以及与实现这些方法有关的模式、实例、查询算法,并对算法的时间复杂度进行了分析。实验结果表明算法是可行的和有效的。
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.
