【摘要】 随着计算机和网络通讯技术的不断发展,如何将各种资源和信息进行统一、有效的管理,进而实现资源和信息的整合分析,从而为上层决策提供事实数据依据越来越成为人们普遍关心的问题。在这种情况下,管理信息系统(MIS,Management Information system)应运而生,同时随着Internet技术的不断发展,基于Internet的B/S架构的管理信息系统越来越成为管理信息系统的主流架构,但是传统的B/S系统在页面的表现力和与用户交互的友好性上越来越不能满足用户的需求。在用户需求的推动下,富客户端B/S架构的管理信息系统的设计和实现技术越来越成为管理信息系统的研究热点。本课题采用当前比较前沿的ExtJs技术,结合Web Service,利用ExtJs提供的数据和显示控件。目的在于开发基于ExtJs富客户端的管理信息系统,替代传统的管理信息系统,改变那些灰色的,方方正正的界面,设计一个功能丰富,操作方便,界面优化,用户体验良好的管理信息系统。本文针对目前传统客户端不能满足当今用户的需求,顺应管理信息系统的发展趋势介绍了基于ExtJs的富客户端的设计与开发。本文的主要工作如下:概括介绍了富客户端和ExtJs框架的相关理论以及他们的发展现状,通过与传统客户端的比较分析,论述基于ExtJs富客户端设计与开发的必要性。总结分析了目前在富客户端领域的技术成果,通过用ExtJs搭建富客户端与其他技术的比较突出了基于ExtJs的富客户端的优越性,并提出基于ExtJs的富客户端管理系统的基本设计思路。详细介绍整个系统的架构和功能模块的设计。并实现基于ExtJs的富客户端的中国海洋大学招投标管理信息系统的所需功能,实现了项目管理、专家管理、供应商管理、专业管理、通知管理、用户管理、文章管理、权限管理、系统设置、统计等功能模块。使网上申请招标、网上报名、参加投标、中标公示一体化。更多还原

【Abstract】 With the development of computer and network technology, more and more people take great attention on how to manage all kinds of resources and information with unified and effective method, and provide factual data for people’s decision. In this case, Management Information System appeared, and with the development of Internet technology, the Management Information System based on internet B/S architecture becomes the mainstream architecture. But traditional B/S architecture Manage Information System cannot meet the needs of many kinds of users on expression and user-friendly interaction. After the needs of users, the design and development about Management Information System which based on Rich client B/S architecture with great expression and friendly user interaction become the focus of research. We hope through the research about rich client Management Information System, this technology can promote the development of Management Information System.In this paper, we use ExtJs technology, data and display controls , combine with Web Service technology to design and develop a rich client Management Information System based on ExtJs technology in order to replace traditional Management Information System. So we can change traditional expression and design a Management Information System which has powerful function, convenient operation and good expression.The traditional Management Information System cannot meet the needs of many different kinds of users, in order to conform the development trends of Management Information System, we design and develop this rich client technology which based on ExtJs technology. The main work of this paper contains:Summarize the related theories of rich client, ExtJs framework and their development trends. Through compare with traditional client technology, discusses the necessity of design and develop the rich client technology based on ExtJs.Summarize and analyze the technological achievements among rich client, through compare the rich client based on ExtJs technology with other technology, we can realize advantage of the rich client based on ExtJs technology. And in this paper, we give out the basic design idea about the rich client based on ExtJs technology.Introduce the whole structure and functions modules. And realize the functions of Ocean University of China Bidding center Management Information System, for example, project management, expert management, announcement management, user management, article management, permission management, system management, statistic management. Users can use this system to ask for bidding, sign up for bidding, participate in bidding and show the winner list. Of course, this system can take good expression, the form can be dragged, expanded, collapsed, sorted and display the interface as user’s idea.更多还原
