摘要:
本文介绍了数据库管理系统 NITDB 的数据更改(插入、删除、更新)功能及其实现技术。提出了一种充分利用查询处理的子系统来提高数据更改处理的效率,使处理过程简单有效的方法,以及应用推迟更新技术来解决更新和删除过程中有关问题的思想。文中还讨论了系统实现视图更新所采用的一种“宏扩展”方法。
Abstract:
NITDB is a multi-user relational DBMS developed on a high-performance microcomputer system in Nanjing Institute of Technology,PRC.Data modi- fication(i.e.insertion,deletion and update)and it’s implementation in the system are presented in this paper.By meaning of the query-processing subsy- stem of NITDB,a simple and efficient method for processing data modification is proposed.In order to solve some problems emerging from processing updete and deletion,a delaying technique is introduced.Besides,a macro-expansion method for view updating is discussed in the paper.
