【摘要】 在信息化过程中,建立企业信息系统是企业信息化的必由之路。优秀的企业信息系统能够增强企业的竞争力,加快我国企业的信息化进程。本文以信息系统为研究对象,利用最新的.NET技术开发面向WEB的企业信息系统,对其开发方法和若干关键技术做了深入的研究和探讨,主要内容和成果如下:对企业信息系统的发展历程和国内外应用现状做了综述,并对其发展趋势做了预测;对企业信息系统的基本理论以及结构化和原型法开发方法做了深入的探讨;然后较深入地研究了.NET框架的工作原理,对.NET中两个主要组成部分ASP.NET和WEB SERVICE的体系结构以及运行机制做了详细的论述,并在与ASP比较后指出了在开发面向WEB的企业信息系统中采用ASP.NET的优越性。在此基础上对采用.NET技术来开发企业信息系统中的一些关键技术进行了深入的研究,详细介绍了在.NET框架下的系统安全管理技术和采用ADO.NET进行数据库操作技术的原理和具体实现过程。最后结合“武钢金属结构有限责任公司企业信息系统”项目,首先介绍了如何利用.NET技术来实现一个办公自动化信息子系统,详细阐述了这个企业信息子系统的系统分析、方案选择、系统设计等具体的过程,并讨论了文件上传、权限管理、数据一致性等关键技术。然后,介绍了一个基于.NET技术的企业即时通讯子系统,详细说明了这个子系统的系统架构、工作原理和系统实现的一些关键技术。更多还原

【Abstract】 In the process of informationalization, it’s necessary for the informationalization of enterprise to establish an enterprise information system. An excellent information system can make enterprise more competitive and expedite the informationalization of enterprise. This thesis takes enterprise information system as a study object and makes a deep and systematic study of some key technologies into enterprise information system. The contents are as follows:The history and the application status of enterprise information system are summarized. Its future trend is forecasted. The basic theory of enterprise information system is deeply discussed. Then the principle of the performance of .NET framework is discussed and the two major components of .NET are introduced in detail. It’s shown that the ASP.NET is prior to ASP in enterprise information system. On this basis some key technologies of developing an enterprise information system with .NET are studied in depth. The technology of system security management and the principle of operation on database with ADO.NET are introduced in detail.At the end of this thesis, combined with the project of ‘The enterprise information system of Wuhan iron & steel Group metal structure company LTD.’, a scheme of Office Automation System is introduced. The process of system analyses, scheme choosing and system design of the Office Automation System and its key technologies are expounded. Then an Enterprise Instant Messaging System based .NET technology is illuminated. Its architecture and the principle of its performance and some key technologies are introduced in detail.更多还原
