OGSA-DAI (OGSA Data Access & Integration):
-Service-based Grid computing middleware.
-Built on OGSA 窶 the Open Grid Services Architecture
-Wraps various relational and XML databases.
-A way of securely exposing data via Web services.
OGSA-DQP (OGSA distributed query processor):
-Provides integration in the form of a distributed query ...
-Uses OGSA-DAI wrappers.
-Also integrates analysis by invoking Web services.
-Declarative interface based on SQL.
-Other benefits include parallelism during query execution.
