144基于ASP的选课系统

摘  要

随着计算机应用的不断普及，计算机网络技术的不断进步和发展。当今随着计算机应用的不断普及，计算机网络技术的不断进步和发展。当今世界，以信息技术为主要标志的科技进步日新月异，高科技成果向现实生产力的转化越来越快。特别是Internet技术的应用和发展， 网络规模的扩大，以及多媒体技术的应用，缩短了人们之间的距离，在为人们提供及时、大量和丰富的信息的同时，也为我们的工作和生活方式带来了巨大的变化。纵观全球经济发展，信息技术和信息产业已经成为经济增长的主要推动力之一，正在改变着传统的生产和经营方式以至生活方式，发达国家经过产业结构的升级和经济结构的转型已进入信息经济阶段。信息资源已经成为国民经济和社会发展的战略资源，信息化水平也已成为现代化水平和综合国力的重要标志。基于网络数据库的学生选课系统是在网络环境的支持下，开展学生选课和信息查询的一种先进模式，发挥学生选择课程的自主性，提高学校课程管理效率。网络选课具有其它技术手段无可比拟的优越性，因此世界各国尤其是发达国家无不对此给予高度的重视。发达国家主要从硬件和实践上建立网络选课环境，并建起信息传递式、合作学习模式等几种主要的选课模式。
本系统使用ASP.NET作为开发工具，MSSQL2005为后台数据库，利用其提供的各种面向对象的开发工具，尤其是数据窗口，能够方便而简洁的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分析，不断修正和改进，直到形成用户满意的可行系统为止。

本系统的目的是学生通过该系统可以了解课程相关信息，进行自主选课，能够满足不同学生对不同题目的不同要求，有利于发挥学生的长处。而且能够充分利用学校的各类教学资源，建立教学激励机制，优化学生知识结构，调动教师与学生教和学的积极性，进一步提高教学质量，提高办学效益。
本系统采用了DAO数据库访问技术,这种技术功能强大，使用方便，节省了大量代码的编写。另外，本系统的主要特色是界面简单友好，操作方便，用户能在很短的时间内掌握其操作。

Abstract
Nowadays, the development of IT, the process and transfer of information also enter into a new stage. Especially, the application and development of the Internet, and expand of the size of the net, the application of Internet on teaching mangement, that shorten the distance of people, while providing the in timing, mass, abundant information for people, it is also bring huge changes for our work and life style, the process and service of technology has become one necessary content of modem in this developing world, the technology of information have being developed very fast especially it has entered into the world of ordinary man.

The choose subject system based on web that is under the support of network is an advanced pattern that the students can choose their subjects and search for information. It also can increase the modem managerial level and capable of competitiveness of university as well as provide the service for the net student and in order to apply the web into the education and use of the web source, advance the balance development of education. Lots of countries take the choose subject system that based on web seriously, they develop the system in hardware and real world, also they develop it in kinds of patterns. This system uses ASP.NET as the developing tools of Microsoft Corporation. MSSQL2005 as the back database and using the developing tools facing all kinds of objects that it provides, especially the data window and it can managing the intellectual objects of data base conveniently and briefly. First, it can set up the system-using model in short time. Then it can carry on the requirement analyze of initial model system and revise and improve continually until form the feasible system that makes the users satisfied. The aim of this system is to let the management of university can carry on efficient management and provide convenient and fast tools for local and managing department, as to get the newest, most completely and most reliable ，information in order to satisfy the students and managements' needing in the largest limitation and to set up a database that data are coincide and highly integrity, as well as its safety is good. As to the latter, it requires that the applicable program's function should integrity and can be used conveniently and the users can master the operation in short time. [资料来源：http://think58.com]
The mainly technological creational point is based on the newest visit technology of DAO database. This technology has strong function, is used conveniently and it can save large code's compile. In addition the main character of this system is that it has new and friendly interface, operating briefly and conveniently and the users can master the operation quickly.
