Administration of the Distributed Query Engine
(DQE) 
The Distributed Query Engine (DQE) is a NetWeaver ‘04 portal service that is capable of simultaneously processing queries to multiple systems. Content developers can write complex queries across different back-end systems, which the DQE can parse and pass to each single system. DQE then puts the results together into one result set.
The portal makes three administration tools available by which the administrator can effect control over certain aspects of DQEoperations.
