Issuing a Query

Monitoring WMS
1. The client application submits a query to the NDCS server.
2. The NDCS server sends compiler estimates of the query requesting permission to execute
to WMS.
3. WMS compares the compiler estimates with the compilation rules set for the service and,
along with other criteria, determines whether to permit the query to start executing.
Figure 1-4 (page 21) shows how WMS handles an incoming query.
