Replication technology, such as Quorum NRW system, is the most effective technology to improve availability of SaaS. However, the variety of SaaS transaction will result in application unbalance. In this paper, we construct a new Quorum NRW system for multi-tenant database which is based on the method of sharing database and schema model. It can provide different R and W values for each tenant according to application transaction features. The paper summarizes the left change and the right change modes according to the differences changes, and proposes Multi-tenant Quorum NRW system which transitive left change method and transitive right change method online. Multi-tenant Quorum NRW system can ensure strong consistency in condition of R + W> N. We design an experimental evaluation of multi-tenant Quorum NRW system, experimental data shows that Quorum NRW system enhances the transaction throughput by 5%-25%.
