基于SaaS模式的信息系统架构优化研究与应用

摘要

SaaS模式作为云计算模式之一，有着多租户且可配置的特点。SaaS模式较好地解决了软件架构在扩展能力与资源共享等方面存在的问题。在研究中以SaaS信息系统架构在数据存储层与访问控制层方面所进行的分析为基础，确定了多稀疏表和键值对结合的模型，探讨了该模型所具有的优势。该研究对优化我国信息系统架构有一定的参考作用。%SaaS model as one of the cloud computing model, have multi-tenancy and configurable features. SaaS model solves the software architecture in expanding ability and the problems of resource sharing, etc. This paper is based on the analysis of SaaS information system architecture in the aspect of data storage and access control layer, of determining the sparse table and keys of combination model, discussing the advantages of the model. The study have a certain reference role on the optimal information system architecture in our country.
