Delphi教学考勤点名系统的设计与实现 摘要：随着科学技术的不断发展，计算机技术越来越成为了教学中不可或缺的一部分。计算机技术正逐步取代传统的方式，为人类带来更多的方便。本系统就是在这样的趋势下所设计的一个信息管理系统，其开发主要包括前端应用程序的开发以及后台数据库的建立和维护两个方面。支持语音的教师上课点名系统是对学生上课情况进行统一的管理，可以方便的进行录入，查询，修改，删除，退出，随时把握学生的上课情况。12707 系统使用Delphi 7.0和SQL Sever 2000作为开发工具，利用微软语音引擎，通过它和相关的语音接口实现了信息录入，语音点名和，点名信息维护，请假管理，数据库备份与还原等必需的功能，其界面友好，可操作性强，使用方便、效率高，并具有修改及扩充功能。 关键词：DEPHI；ADO；语音引擎；SQL Sever 2000 毕业设计说明书（论文）外文摘要 TitleDesign and Implementation of the attendance roll call system in general teaching Abstract With the continuous development of science and technology，computer technology has increasingly become an integral part of teaching. Computer technology is gradually replacing the traditional way for human beings to bring more convenience.this system is an information management system designed in such a trend. For the former, it requires the function of the application procedure is complete and easy to use. For the latter, it requires to set up a data base whose data is consistent and integrated and secure. The roll call system for the teachers in classes which supports the speech sounds is a unified management of the students. It can school, enquiries, modify, delete and withdraw conveniently. It also can master the situation of the students in classes in any time. This paper uses Delphi 7.0 and SQL Sever 2000 as the development tools , realizes the voice roll call by taking the use of the Microsoft speech engine and its related voice interface, the system carries out the information to record to go into, speech roll call and cast shadow the roll call, have a roll call the information maintenance and have a roll call the after the event to re-appear, essential functions such as the database backup and revivification etc. the operation is simply. the interface is friendly,easy to operate and use,and has the Modifications and extensions. 4.3.2数据库的连接22 5系统实现22 5.1教师课程选择界面23 5.2功能选择窗体24 5.3点名界面24 5.4请假管理界面27 5.5信息输入与修改模块28 5.6数据备份还原28 6软件测试30 6.1测试范围与主要内容30 6.2测试过程31 结论33 致谢34 参 考
