6 Performance Evaluation

In [ 24 ] we have explored the potential of using EET multi-tenant database schema, and
we performed several experiments to assess the effectiveness of EET by comparing it
with Universal Table Schema Mapping (UTSM), which is one of the multi-tenant
database schema techniques implemented commercially. Signi

cant performance
improvements were observed using EET when compared to UTSM, making EET
schema a good candidate for the management of multi-tenant data in SaaS applications.
In this paper, ve types of experiments were performed to verify the practicability of
