学校田径运动会管理系统是典型的信息管理系统，本系统为田径运动会运动会组织者提供方便、快捷的方法，系统的对运动会进行合理的安排与管理，实现无纸化工作，节省大量人力和物力。本论文首先使用了Visual Basic作为开发工具和Access作为后台数据库，然后再介绍了开发背景，最后通过截图和表格来说明该系统的开发与操作。设计充分利用VISUAL BASIC以及ACCESS数据库易于使用和快速开发的特性，提高了编程效率和可靠性。同时对系统的开发原理、系统的功能特点和设计方案进行了介绍。在对运动会管理体系进行充分分析和系统论证的基础上开发。它不但能完成运动会管理中的基本操作，而且具有程序设计合理、操作简单、运行可靠、保密性强等特点。-The sports meeting administrative system of track and field is a typical information management system. It makes games management simple and convenient for organizer to arrange and manage the games with reason. It makes no-paper work possible, and save a lot of manpower and material resources. This paper use "Visual Basic" as the development tool and "Access 2003" as the background data base first, then introduce the background of development, and the developing and operating of the system through photographs and charts. Design the characteristic fully utilizing VISUAL BASIC and ACCESS database to be apt to use and develop fast to improve programming efficiency and dependabil
