One central idea of Software-as-a-Service (SaaS) is utilizing the multi-tenant efficiency to catch the "Long tail" of market; however, there exists a common challenge while transforming legacy web applications from single-tenant architecture to multi-tenant one, especially when dealing with large amount of data access objects.
