| 摘 要： | 时态信息处理是当前信息处理的主要研究方向之一，时变信息的表达与应用是时态信息处理的关键技术。文中利用RDBMS系统实现时态信息的表达和时态信息的基本应用，通过基于MS SQL的结构化语言实现时态信息处理，特别是对于记录时变属性的时间变元Now的有关操作进行了设计，表达了时态变元Now的即时变化的语义。

| Abstract: | Temporal information processing is one of the import.an, t information manipulation research branches, the presentation and application on time-varying information is the key technology of temporal information processing. The paper, based on RDBMS, realizes the storage and basic application about the temporal information. By realizing the temporal information processing based on MS SQL as well, especially giving a valid project to realize the semantics of temporal key variable Now, time-changed variable semantics are imitated efficiently. |
