摘 要 开发数据库题库管理系统主要是为了建立一个统一的题库,并对其用计算机进行管理,使教师出题高效、快捷。 其开发主要包括后台数据库的建立、维护以及前端应用程序的开发两个方面。对于前者要求建立起数据一致性和完整性强、数据安全性好的库。而对于后者则要求应用程序功能完备,使用方便、灵活等特点。经过分析,我们使用 Microsoft公司的SQL Server7.0 管理后台数据库。用Visual Basic6.0中文版做为前端开发工具,利用其提供的各种面向对象的开发工具,尤其是数据窗口这一能方便而简洁操纵数据库的智能化对象,首先在短时间内建立系统应用原型,然后,对初始原型系统进行需求迭代,不断修正和改进,直到形成用户满意的可行系统。在开发过程中使用了ADO技术和SQL语言完成了对系统功能的实现。 数据库题库管理系统包括六个模块,实现对题库的录入、编辑、查询和自动生成试卷、手工生成试卷、输出试卷等功能。同时还增加对所用教材的管理如教材的录入、编辑和查询,功能的扩展如试题类型的增加和系统的更新。达到了开发数据库题库管理系统的目的。 本系统具有针对性强、操作简便、成卷快、题目搭配合理、试卷难易程度可控等特点。相信投入使用后定会成为教师出题的好帮手。 关键词:数据库题库管理系统;题库;ADO;SQL;VBA。 AbstractThe system of managingdata base of examination question bank is a typical application of managinginformation system (know as MIS),which mainly includes building up data-base ofback-end and developing the application interface of front-end. The formerrequired consistency and integrality and security of data. The later shouldmake the application powerful and easily used. By looking up lots of datum, we selectedVisual Basic presented by Microsoft because of its objective tools in Win32. VBoffered a series of ActiveX operating a data-base. It can give you a short-cutto build up a prototype of system application. The prototype could be modifiedand developed till users are satisfied with it. And we also selected SQLServer7.0 presented by Microsoft in order to manage data-base. We utilizedtechnology of ADO and used Structured Query Language to develop this system. The system of managing data base of examination question bankincludes six modules, such as register, managing information, edit, query,output module and so on. Key words: system of managing database of examination question bank;data base;ADO;SQL.
