摘要

概述了在时态数据库环境中定义和维护视图的方法和机制。视图定义语言通过允许布尔运算符和比较运算符的操作数为一组间隔来扩展它们。本文提出了一种维护时态视图的机制，结果表明，时态数据库视图的维护问题远远少于标准的关系数据库视图。

On the definition and maintenance of database views with time-varying domains

An approach and a mechanism for the definition and maintenance of views within temporal database environments are outlined. The view definition language makes use of extending Boolean and comparison operators by allowing their operands to be sets of intervals. A mechanism for maintaining temporal views is presented, and it is shown that temporal database views have far fewer maintenance problems than their standard relational counterparts.<>
