Research Of Credit Bank Sysytem On Saas Multi-tenant Model

This project uses "Credit Bank application and research" which is a subsystem of"Full service of technical trading system development and demonstration" launchedby Beijing Science and Technology committee as the background. By participating inthe project with analyzing, researching, designing and developing, I understand thecredit bank concept and system function deeply, which guide me to writing this paper.Credit Bank is a combination of educational informationization and lifelongeducation, our Country hopes by building such a system, that could certificatepersonal learning outcomes without a definite form (such as work experiences,learning experiences, various of professional certificates) through Common Criteriacertification to certain credits, and storage to personal accounts; Different educationalinstitutions and major schools can achieve mutual recognition of related coursesthrough the mutual recognition system, credits are translated by a certain percentage;By accumulating credits in learning period, when credits reach the academicrequirements, one can apply for a diploma certificate.Based on inspection and make in-depth study of literature, This paper proposes amethod which apply the SaaS (software as a service) multi-tenant model into creditbank system, each school apply to become a tenant of this system, and finish dailybusinesses by connecting the system with a web browser, which has been built bySaaS service providers. Schools do not care about the deployment of software,establish of the platform and maintenance of the system, simply renting the system asneed, paying for it according to usage. SaaS multi-tenant model achieve singleinstance several times of application, that is, all schools share this credit bank system,by the design of back-end database, realizing isolation and sharing of data betweentenants.Firstly, by studying traditional bank and credit management system architecturemodel, then combining researches with credit-data segmentation management andsystem security, I propose database model which adapt to the SaaS multi-tenant modeland credit bank system architecture model. Finally, I fulfill the development of creditbank system, while the system is deployed on Microsoft’s Windows Azure Platform,providing for the tenant. Based on SaaS Multi-tenant model, the system can not only reduce constructionand maintenance difficulty, while providing inter-school classes and creditsrecognition features that make educational resources can be shared.
