网上选课系统 摘要： Internet网是目前全球最大的计算机通信网，它遍及全球几乎所有的国家和地区。www系统是一个大型的分布式超媒体信息数据库，它极大的推动了Internet的发展，己经成为Interne中最流行、最主要的信息服务方式。www技术之所以能在全球普及，一个重要的原因就是它与数据库管理系统相互融合，成为一个处理和共享信息的强大工具。一方面，数据库是一种强大的信息管理工具，另一方面，www提供了共享数据的方法。两者强强联合取长补短，发挥各自优势，使用户可以在Web浏览器上方便地检索数据库的内容。 (MIS),其开发主要包括后台数据库的建立和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,易使用等特点。利用其提供的各种面向对象的开发工具,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。本系统可以方便老师、。实现全校学生在线查询。还可以对新来的学信息进行信息录入。由于学上课情况复杂，可以实现信息修改，及时调整学的基本情况。 学生 数据库 查询 Abstract : The Internet is the worlds largest computer communications network, network It throughout the world in almost all countries and regions. Www system is a large-scale distributed hypermedia information database It has greatly promoted the development of the Internet, the Internet has become the most popular, The main methods of information services. Www technology has the global reach, and a major reason is its database management system integration, as a processing and sharing of information a powerful tool. The one hand, the database is a powerful information management tools, on the other hand, www provide data sharing methods. Taken a strong alliance with other countries to play to their respective advantages, allow users to the Web easily searchable database content. Browser This paper mainly students Elective System program analysis and network planning, The system is a typical management information system (MIS), including development of its key database background to the establishment and maintenance of front-end applications and the development of the two areas. Regarding the former requirement to establish data consistency and integrity of strong data security for good. As for the latter demanded the application functions, and easy-to-use features. Use of the various object-oriented development tools, the first system in a short period of time to establish a prototype application, and then the initial prototype system needs iteration, and constant
