摘要： 摘要.随着数据库应用的日趋广泛,终端用户需要友好的用户接口.一个可视的用户接口通过对数据库模式进行简单的可视表示,可使用户直观地与系统交互、操纵数据、开发程序.目前,对数据库可视接口的研究尚处于起步阶段,还没有统一的认识和方法.本文围绕用C++语言实现数据库可视接口VID的整个过程,探讨了面向对象方法在开发可视接口原型时的作用.文章首先简单地介绍了VID的适用范围、与DBMS的关系,着重介绍了VID的功能特性,然后描述如何使用面向对象语言C++的特性,特别是用继承性、多态性来加速VID的开发.＊

Abstract: As database is used more broadly, various end-users need more friendly user interface. An inter-face to provide a simple visual representation of database schema can meet their needs with which users can ma-nipulate data and develop their own program by interacting visually with database.Since research for visual database interface is still in infancy so far, there is no unified understanding and development methods.This paper discusses the merits of an object-oriented method (C++) as a prototyping tool to implement a Visual Interface for Database (VID) . After briefy describing the usage scope of VID and the relationship between VID and DBMS, wediscuss some essential features of VID and how to use characteristics of C++ such as inheritance, and polymophism for expediting the development.
