The user's response time was an important indicator for the heterogeneous database which locate in the different network. This paper describes the structure of the distributed heterogeneous database system of query optimization system based on the Hibernate technical for the B/S structure, and analysis the calculation of the response time. Finally an example was used to demonstrate the feasibility and practicability of query optimization.
