The Research Of System Architecture Of Tenants And Key Technologies Under SaaS Model

Software applications and service model that has evolved from computer software, software customization, and then to third-party applications hosted (ASP) of constant change. In particular, in recent years, the concept of SaaS software service is getting more attracted wide attention both whthin and outside of the industry.SaaS (Software as a Service) which means the software as a service, goes along with the development of Internet technology and applications continue to mature, but began to rise in the 21st century, a completely innovative software model. Compared with traditional software service model, SaaS service provider build the platform in which all the necessary network infrastructure and hardware and software operating can exit for enterprise. ASP is also responsible for all pre-and post-implementation maintenance services. This not only significantly reduces the overall enterprise information cost of ownership (TOC), also allows companies to focus more focused on compliance and support of business goals to high-value activities. That's why SaaS can have attracted the attention of the majority of enterprises since it came out, especially SMEs, attention, and is considered the best small and medium enterprise information solutions.As the features of SaaS, multi-tenant lead to the differences between traditional and modern technical architecture and software. In consideration of this, the paper is to carry out the corresponding research around the multi-tenant, SaaS model system architecture and key technology with in-depth analysis of SaaS model of software applications and traditional software applications. The study includes:SaaS model architecture design, SaaS model database schema design, and multi-tenant technology, data extension technique, the configuration-based technology and scalable technology, and other key support technology implementation. Combinding with a specific project, a SaaS model Prototype System is constructed according to research performed to confirm the results.Currently, SaaS model is still in the theoretical exploration and early stage of development, coupled with the limited due to time and their own level, thesis work is still lack of depth in some areas, and there are some shortcomings. We will be give continuous improvement should in the follow-up study.
