【摘要】：當(dāng)前市場流行的會計(jì)記賬軟件，主要是以C/S架構(gòu)設(shè)計(jì)并實(shí)現(xiàn)的，，少部分是以B/S架構(gòu)設(shè)計(jì)實(shí)現(xiàn)的。與C/S架構(gòu)相比，B/S架構(gòu)具有易升級維護(hù)、易安裝部署、較低維護(hù)成本的優(yōu)點(diǎn)，但是對于中小企業(yè)而言，這些成本依然顯得較大，所需技術(shù)依然顯得復(fù)雜。 論文針對目前市面流行的財(cái)務(wù)記賬軟件所具有的上述問題，采用云架構(gòu)，基于SaaS理念設(shè)計(jì)和實(shí)現(xiàn)了網(wǎng)上財(cái)務(wù)記賬系統(tǒng)。將軟件的安裝、維護(hù)、升級等工作集中在云端；免去了企業(yè)用戶的大量工作，使企業(yè)僅僅需要使用軟件服務(wù)，無需其他工作，極大降低了企業(yè)的記賬成本。 網(wǎng)上財(cái)務(wù)記賬系統(tǒng)采用當(dāng)下主流的J2EE平臺，利用典型的SSH架構(gòu)，基于SaaS理念設(shè)計(jì)，實(shí)現(xiàn)并部署在云計(jì)算平臺中。系統(tǒng)的設(shè)計(jì)目標(biāo)是搭建完整、易用的企業(yè)記賬軟件。 從用戶角度來說，企業(yè)通過購買記賬服務(wù)，即可隨時(shí)在任意一臺電腦上使用瀏覽器，開始日常記賬工作。 從服務(wù)商角度來說，軟件部署在云計(jì)算平臺中，免去了繁復(fù)的機(jī)房維護(hù)、頻繁的數(shù)據(jù)備份、高昂的前期投入；專心致力于提供優(yōu)異的軟件服務(wù)。 由于系統(tǒng)需要服務(wù)于眾多獨(dú)立企業(yè)用戶，所以軟件使用環(huán)境非常復(fù)雜。前端采用EXTJS富客戶端技術(shù)，不僅使得瀏覽器之間兼容性得到了提高，也使用戶體驗(yàn)得到了保證。 由于各個(gè)云計(jì)算平臺提供商所實(shí)現(xiàn)的數(shù)據(jù)庫，與傳統(tǒng)數(shù)據(jù)庫大多具有較大差異，系統(tǒng)需優(yōu)化數(shù)據(jù)庫層，適應(yīng)云平臺數(shù)據(jù)庫，提高系統(tǒng)效能。 為應(yīng)對龐大的訪問量，項(xiàng)目將部署在云計(jì)算平臺上使用彈性服務(wù)器集群；根據(jù)訪問量多寡，自動配置相應(yīng)服務(wù)器數(shù)量，節(jié)約成本的同時(shí)保證用戶體驗(yàn)。
[Abstract]:The current market popular accounting software is mainly designed and implemented with C / S architecture, and a few parts are designed and implemented by B / S architecture. Compared with the C / S architecture, the B / S architecture has the advantages of easy to upgrade and maintain, easy to install and deploy, and low maintenance cost, but for small and medium-sized enterprises, these costs are still large and the required technology is still complex. Aiming at the above problems of the current popular financial accounting software in the market, this paper designs and implements the online financial accounting system based on the concept of SaaS. The installation, maintenance and upgrade of the software are concentrated in the cloud, which eliminates a large amount of work from the enterprise users and makes the enterprise only need to use software services without any other work, which greatly reduces the cost of accounting. The online financial accounting system adopts the current mainstream J2EE platform, uses the typical SSH architecture, and is designed based on the idea of SaaS to realize and deploy in the cloud computing platform. System design goal is to build a complete, easy to use business accounting software. From the user's point of view, the enterprise can use browser at any time on any computer by purchasing bookkeeping service. From the service provider's point of view, the software is deployed in the cloud computing platform, which avoids the complicated maintenance of computer room, frequent data backup, high early investment and dedicated to providing excellent software services. Because the system needs to serve many independent enterprise users, the software usage environment is very complex. The front end adopts EXTJS rich client technology, which not only improves the compatibility between browsers, but also guarantees the user experience. Because the database implemented by each cloud computing platform provider is quite different from the traditional database, the system needs to optimize the database layer, adapt to the cloud platform database, and improve the system efficiency. In order to cope with the huge traffic, the project will be deployed on cloud computing platform using flexible server cluster; according to the number of visits, automatically configure the corresponding number of servers, save cost and ensure the user experience.
