摘要
SD-DOOD是一个演绎对象数据库实验系统。论文主要是设计并实现了系统的动态更新数据库功能,文中首先给出了详细的实现更新的算法,进而对算法进行了简单分析,最后通过举例说明了这个功能。系统中采用自底向上和自顶向下相结合的更新方式,增强了系统的安全性。
SD-DOOD is a deductive object-oriented database experiment system.In the paper,the function of dynamic updating database is designed and realized for the system.Firstly,Particular algorithms for updating system have been put forward.Secondly,the algorithms have simply been analyzed.Lastly,the function is shown through illustrate.The method combining bottom up and top-down is used in the system SD-DOOD.It can improve security of the system.
