摘要:随着计算机及⽹络技术的迅猛发展和应⽤,应⽤软件在诸多应⽤领域中占据⽇益重要的地位。管理信息系统(MIS)也被⼴泛应⽤到各⾏各业。政府机构,企事业单位也正加快信息化建设,以提⾼⼯作效率和管理⽔平。⼯程施⼯⾏业是⼀种分⼯细致和劳⼒密集的⾏业。⼯程管理具有施⼯⼈数众多、⼯序繁复、分散性、移动性和⼀次性等特点。根据欧美国家有关调查统计显⽰:在传统管理模式下,⼯程设计⼈员每天约有35%左右的⼯作时间花费在查阅图纸资料及交流协调上;⼯程施⼯管理⼈员往往需要花费多达50%的⼯作时间⽤来搜查必要的信息和信息交流,严重降低了⽣产效率。灵活地组织管理技术⽂档,共享设计信息资源,快速、准确地协同设计与施⼯,使⼯作流程⾃动化也已成为提⾼⼯作效率的当务之急。为了和国际接轨,⼯程施⼯⾏业迫切需要采⽤先进科技、强化科学管理和加速信息化。

管理信息系统的使⽤可以为组织的管理和决策提供有⼒的依据,并最终提⾼⼯作效率和经济效益。本⽂主要围绕着.NET平台的核⼼技术进⾏,先从介绍.NET框架开始,对其核⼼C#.NET和http://www.doczj.com/doc/d143914c6aec0975f46527d3240c844769eaa08a.html 进⾏了研究,然后应⽤其关键技术,对项⽬管理信息系统进⾏了深⼊研究,并对其编程实现。最后,对系统现阶段的研究设计成果进⾏总结,展望了下⼀步的⼯作和研究⽅向。本系统采⽤Visual C#.NET为开发语⾔,后台数据库为Microsoft SQL Server2000,采⽤基于B/S的三层结构,将系统分成三层:⽤户界⾯层、业务逻辑层、数据层。

项⽬信息是⾮常关键的资源,在当今的计算机与互联⽹迅速发展的背景下如何利⽤现代IT技术进⾏管理值得思考。本⼯程项⽬信息管理系统的开发、研究能够I

房地产信息管理系统的设计与实现Abstract

With the rapid development and application of computer and network technology, application software occupy anincreasingly important position in many application areas. Management Information System (MIS) has been widely applied toall walks of life. Government agencies, enterprises and institutions also are speeding up the construction of informationtechnology to improve the efficiency and management level. Construction industry is a meticulous division of labor and labor-intensive industries. Construction project management has numerous number of complicated processes, dispersion, mobilityand disposable features. According to the survey statistics show that European countries: In traditional management,engineering staff every day about 35% of working time spent on the exchange of information and coordination of inspectiondrawings; construction management personnel often need to spend as much as 50% of working time to search for necessaryinformation and the exchange of information, severely reducing production efficiency. Flexible organization and managementtechnical documentation, share design information resources, quickly and accurately collaborative design and construction,so that workflow automation has become imperative to improve work efficiency. Order and international standards, theconstruction industry, an urgent need to adopt advanced science and technology, strengthen scientific management andacceleration information.

Use management information system can provide a strong basis for the management and decision-making organizations,and ultimately

In this paper, revolves around the core technology of the .NET platform will be,starting with the beginning introduces .NET Framework, C # .NET and its corehttp://www.doczj.com/doc/d143914c6aec0975f46527d3240c844769eaa08a.html were studied, and then apply the keytechnology, project management information system in-depth study, and its programming. Finally, the results of research anddesign stage of the system is summarized, and the prospect of future research directions of work. The system uses Visual C# .NET as a development language, backstage database is Microsoft SQL Server2000, based on B / S three-tier structure,the system is divided into three layers: the user interface layer, business logic, data layer.

Project information is a critical resource in the rapid development of today's computers and the Internet how to use modern ITtechnical background to manage worth considering. Development of the Project Information Management System, researchproject information can be obtained and efficient management, thereby enhancing the operational efficiency of the entireproject, the project thus enhance their market competitiveness.
