基于MVC模式设计和实现科技情报管理系统
摘要
本系统是基于MVC模式设计实现科技情报管理系统,的高速发展,产生了各种各样的技术,MVC模式是最具有发展前景的,MVC是把一个应用输入、处理、输出流程按照Model、View、Controller的方式进行分离,这样一个应用被分成三个层——模型层、视图层、控制层。大部分用过程语言由于数据页面的分离不是很直接,因而很难体现出业务模型的样子或者模型的重用性。产品设计弹性力度很小,很难满足用户的变化性需求。MVC要求对应用分层,虽然要花费额外的工作,但产品的结构清晰,产品的应用通过模型可以得到更好地体现。
论文主要介绍了本课题的开发背景、开发环境、相关技术以及开发的重点与难点。本系统通过运用JSP、MVC等技术实现了对整个系统的后台管理和用户的查询工作,其中后台管理包括用户管理、文章管理、用户查询等功能,使该系统具有了良好的安全性和可维护性,充分发挥了JSP、MVC等技术的优越性,保证了系统能够正常稳定的运行。

Abstract
Built on the model of MVC, this system is used to achieve plete management of the data and information of science and technology. Nowadays a wide range of advanced technologies emerge along with the rapid development of the , and of all the new technologies the MVC model has the most bright future. MVC separates the management of input application t, processing, and output according to the pattern of Model, Viewer and the Controller. This application is divided into three layers – the model, the view and the control. And most of the using language processes can not reflect essfully what the business model is like or its importance. So there is not so much flexibility in the design of products and they can never meet users’ various and changeable demands. MVC must have the application layered first of all, it may need some extra work but products are clear structured and the application model can be better reflected.
The thesis mainly introduced the background, environment and important and difficult points of the development and technologies related about this topic. The system possess favorable security and maintainability by exert JSP、MVC technique which ensure the system runs in gear and steady and it achieves the structure of management in backstage and inquires on the stage, possess the functions of user management, information management and
information inquire, which enable the system ‘s qualities of high security a
