【摘要】 化工数据内容庞杂，数据库的设计是化工计算软件的重点和难点，本文提出用ＴｕｒｂｏＰｒｏｌｏｇ语言外部数据库技术实现基于磁盘的数据库管理系统的设计方法，解决了数据库庞大与微机内存不够的矛盾。算模块可方便地通过接口从本数据库中调用数据，实现了友好的用户界面，提高了数据库管理的效率和透明性。更多还原

【Abstract】 This paper provides a method of design database management system design, which is base on disk by external database technique, This database system solved the contradiction between Iarge database and small memory. In addition, programme for separation process simulation can get data from the database system conveniently.更多还原
