摘  要
“信息化一小步，企業(yè)一大步！”這是目前各類企業(yè)的共同認識。隨著全球經(jīng)濟迅猛發(fā)展，產(chǎn)業(yè)競爭格局逐步形成，中小型企業(yè)比大型企業(yè)更需要借助信息化手段來利用全球的市場、研發(fā)等資源實現(xiàn)其快速發(fā)展。目前市場上專門針對中小型企業(yè)的管理類軟件產(chǎn)品始終較為匱乏，從功能上來看，ERP、CRM等大都是針對大型企業(yè)，其系統(tǒng)模塊復雜度高、技術(shù)人才能力要求高、部署資金多、風險高，對于業(yè)務流程相對簡單、應用需求相對單一、專業(yè)技術(shù)人才和資金均缺乏的中小型企業(yè)來說, 是不合適的。
伴隨著計算機技術(shù)以及網(wǎng)絡技術(shù)的發(fā)展，SaaS（軟件即服務）模式脫穎而出。SaaS模式為中小型企業(yè)低成本、高效率地應用先進技術(shù)實施信息化建設提供了最佳捷徑。SaaS模式下，軟件供應商將應用軟件統(tǒng)一部署在自己的服務器上，負責軟件的維護和升級，并且基于Internet提供軟件服務，企業(yè)按需租用軟件相應模塊、按租用的服務付費，無需承擔軟件的軟硬件維護和升級、投資的巨額風險等。
SaaS模式獨特的應用服務模式使得SaaS模式下的軟件在設計時必須面對多用戶界面、多處理邏輯、多數(shù)據(jù)結(jié)構(gòu)的難點，從而也使得對基于SaaS模式的軟件的設計和開發(fā)具有研究意義。
本文前半部分就SaaS作出理論研究，就什么是SaaS、SaaS模式的相關(guān)特征作出說明。在對這些內(nèi)容充分理解的基礎上，在本文的后半部分中在適合SaaS的軟件設計方式指導下，使用適合SaaS的軟件開發(fā)工具對SaaS模式下的企業(yè)信息化管理平臺進行了構(gòu)建實現(xiàn)。在實現(xiàn)過程中首先研究了SaaS模式下企業(yè)信息化管理平臺的特點，在此基礎上進行了需求分析，選取了平臺實現(xiàn)的架構(gòu)，完成了平臺的功能模塊設計、數(shù)據(jù)庫設計，給出了系統(tǒng)實現(xiàn)的部分流程及界面。在本文最后就本論文目前的研究情況及后續(xù)的研究方向作出了總結(jié)。

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, R&D 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 and software maintenance and upgrades, and more investment risks.
when designed, the unique application service of SaaS model makes the SaaS model software face a difficulty in multi-user interface, multi-processing logic and multi-data structures,thus makes a significance of research on the base of software design and development.
The first half of the article makes a theoretical research on SaaS, on what is a SaaS, what are the features of SaaS module. On the basis of understanding of them, in the second half of this article, under the guidance of ways of the SaaS software design, tools that are suitable for SaaS module have been used to build the information management platform for enterprises. During the implementation process, this article firstly studied features of enterprise's information management platform in the SaaS mode, based on which,did some demanding analysis, selected structures to realize the platform, completed the moduel design of the platform functions, as well as database design,and gave the part of process of system implementation and interface. At the end of this article,it drew a conclution on the subject of current research and the direction to the following research.
