Studies for optimization of data analysis queries for HEP using HERA-B commissioning data
MetadataShow full item record
In this paper we present an overview of the ongoing studies to build up a framework that supports the analysis after the reprocessing phase. This framework aims to develop a standard data query language for the HEP community. The related studies have been considering the relational database model as possible approach opposed to the object model. Several optimizing and tunning techniques are being used in technologies like DB2, Oracle and Root, that are simultaneously being evaluated. The experience obtained can be seen as a valuable testbed for the future LHC and simultaneously as interesting input for the development of the GRID.
