计算机技术硕士毕业论文--SaaS模式下企业信息管理平台的研究与实现.doc

摘 要 , 是不合适的。 伴随着计算机技术以及网络技术的发展，SaaS（软件即服务）模式脱颖而出。SaaS模式为中小型企业低成本、高效率地应用先进技术实施信息化建设提供了最佳捷径。SaaS模式下，软件供应商将应用软件统一部署在自己的服务器上，负责软件的维护和升级，并且基于Internet提供软件服务，企业按需租用软件相应模块、按租用的服务付费，无需承担软件的软硬件维护和升级、投资的巨额风险等。 SaaS模式独特的应用服务模式使得SaaS模式下的软件在设计时必须面对多用户界面、多处理逻辑、多数据结构的难点，从而也使得对基于SaaS模式的软件的设计和开发具有研究意义。 本文前半部分就SaaS作出理论研究，就什么是SaaS、SaaS模式的相关特征作出说明。在对这些内容充分理解的基础上，在本文的后半部分中在适合SaaS的软件设计方式指导下，使用适合SaaS的软件开发工具对SaaS模式下的企业信息化管理平台进行了构建实现。在实现过程中首先研究了SaaS模式下企业信息化管理平台的特点，在此基础上进行了需求分析，选取了平台实现的架构，完成了平台的功能模块设计、数据库设计，给出了系统实现的部分流程及界面。在本文最后就本论文目前的研究情况及后续的研究方向作出了总结。 关键词：ABSTRACT Information technology a small step, enterprise one step! This is a common sense for all types of enterprises. With the rapid development of the global economy, the pattern of industry competition has formed gradually. Small and medium enterprises need to take advantage of global markets, RD resources to achieve their rapid development more than large enterprises by use of information technology. Currently the management of products, specifically for SMEs, has always been relatively scarce on the market.From the functional point of view, ERP, CRM, etc are mostly for large enterprises, whth its high systems modules, high capacity and technical requirements, more funds and risk. It is inappropriate for SMEs running a relatively simple business process,having single demand and application,or lacking both professors in technology and funds. With computer technology and network technology, SaaS (software as a service) model stand out. SaaS model provides the best shortcuts for small and medium businesses which make informational construction by means of advanced technology with low cost and high efficiency.In the SaaS module, the application software will be arranged for its server by software vendors.It is responsible for software maintenance and upgrades, and provide Internet-based software services. Enterprises hire a corresponding module in accord with their demand, pay for services by leasing, without commitment to the hardware
