Grid Services for Fast Retrieval on Large Multidimensional Databases [chapter]

Peter Baumann
2001 Lecture Notes in Computer Science  
The basic approach is to augment the highvolume data generators with a database system for the management and extraction of spatio-temporal data.  ...  Implementation of this platform relies on the multidimensional database system RasDaMan. Evaluation covers all major application fields by HPC centres with in-depth experience in their resp. field.  ...  Applications accessing HPC data have to deal with directories, file names, and data formats instead of accessing spatio-temporal data in terms of, say, simulation space-time and other user-oriented terms  ...
