摘要
面向对象数据库作为第三代数据库,具有前两代数据库无法比拟的优点,满足复杂数据结构和海量存储需要,是新型数据库如多媒体数据库﹑空间数据库﹑演绎数据库﹑工程数据库的实现基础。本文作为综述第1部分,通过对比传统数据库不足来说明面向对象数据库优点,介绍面向对象数据库3种关键技术:数据库转换﹑模式演进﹑视图实现,阐述其原理并评论其优缺点。
OODBS that is called the third DB has excellent advantages compared with the former two generation DBo It satisfies with demand of complicated data structure and mass storage ,which is the base of designing some new DB such as multimedia DB,space DB,deduction DB,engineering DB and so on o As the first part of this paper,we firstly show the merit of OODBS through comparing the deficiency of traditional DB ,secondly introduce three key technology of OODBS： DB switch ,model evolvement,view realization, with expatiating their theory and remarking on their merit and deficiency.
