Abstract :
The considerable growth of online document searching and consulting brings many data providers to reconsider their database management system (DBMS) capacities. Parallel DBMSs then appear as a good solution, but the involved changes in administration and costs limit their breakthrough. To overcome these drawbacks, we propose a hybrid structure which adapts a parallel extension to an existing DBMS. This extension cuts down the amount of work of a sequential DBMS by parallelizing the incoming queries over a network of workstations. To allow this parallel execution, data are replicated over the stations according to a specific strategy. We describe this strategy and then examine the parallel query optimization
