A transparent data middleware in support of multi-tenancy

The upcoming business model of providing Software as a Service (SaaS) not only creates new challenges for service providers but also for software engineers. Data is at the heart of SaaS. Therefore, multi-tenancy data architecture becomes hot topic. However, most tenant data solutions only solve part of the problem and focus on isolation and sharing. In this paper, we present an architecture that enables multi-tenancy at the database driver level, which enable tenants to run their applications in a multi-tenant framework. This approach is transparent for the application. Additionally, the architecture and analysis are discussed in detail.
