摘要： 根据时态数据库的原理,提出了通过中间件TDBASE和非时态数据库管理系统交互实现时态处理的设计思想,描述了TDBASE所支持的时态语法和TDBASE的实现过程。用户可以通过TDBASE所提供的接口,把具有时态语义的SQL转换成标准的SQL后交由非时态的数据库管理系统运行,从而实现了该数据库管理系统的时态处理功能和其管理下的时态数据库。

Abstract: According to the theory of temporal database,a design idea of realizing temporal dispose by communicated between TDBASE,a temporal disposal middleware,and non-temporal DBMS is offered. The temporal syntax supported by TDBASE and the process of realizing TDBASE are described. By using the interface offered by TDBASE,user can translate temporal SQL into standard SQL that could be run by non-temporal DBMS in order to realize a DBMS that can dispose temporal data and several temporal databases managed by it.
