微机数据库主语言系统的设计和实现

Design and Realization of Host Language System of Microcomputer Data Base

目前,对于微机数据库dBASE自含主语言中存在功能不足的问题已有不少解决方法,但大多数局限于与高级语言进行数据文件对接,只能局部地增加主语言的功能。本文参照大型数据库的构造方式,直接选用已有的高级语言作为主语言,从而使dBASE置具有绘图、通信、进行复杂计算等功能。文中给出了一个dBASEⅢ以GWBASIC力主语言的实例。

Many methods have been developed to remeay the defects of oneself host language dBASE used as database language in microcomputers,(?) most of them are based on the transmission of data files betwseen dBASE and other high level languages,and that can only partly add functions to the host language.Consulting the building method of large-scale database,this paper describes a new method which enables the dBASE to possess such functions as drawing,communication,complicated computation by directly selecting one available high level language as the host language.An example with GWBASIC as the host language is given in the paper.
