SUN工作站电网调度系统中数据库管理系统的设计与实现

本文介绍以电网调度自动化为背景，基于ＳＵＮ工作站设计并实现的一个数据库管理系统，该系统使数据根据存取速度要求被选择以内存共享段形式或磁盘文件形式存储，由系统提供统一的定义模式和操纵模式，本文主要从数据库词典管理，内存数据管理，磁盘数据管理三方面介绍系统设计的实现方法，并从中探讨在ＳＵＮ／Ｕ－ＮＩＸ环境下实现记录实时，快速存取的技术和方法。

DBMS ON SUN STATION FOR THE USE OF AUTOMATION OFELETRIC POWER SYSTEMS-DESIGN AND IMPLEMENTATION

In this paper,a DBMS implemented on Sun station is presented which is designed according to the requirment of automation of electric power systems. For this DBMS,datas can be selected to be stored in disk or memory with the restriction of accessing speed, but a common definition pattern and operation pattern are provided.We introduce the design and implementation method of the DBMS mainly from three aspects,such as dictionary manage,memory data manage and disk data manage,in which we study and analyze some techniques and methods used for implementing the high speed accessing in SUN/UNIX system.
