In the summer of 1999, ATLAS undertook a pilot project to develop
object-oriented software that would simultaneously support tile
calorimeter testbeam data analysis and provide a testbed for
evaluation of candidate ATLAS software strategies. Strategies related to
object persistence and to transient/persistent separation were of particular
interest.
Among the distinctive features of the resulting architecture are its
detector-centric view, which allows physicists to focus on the detector
when appropriate and permits the event model to remain opaque, and its
ability to support multiple distinct transient/persistent mapping
strategies concurrently. The software has been successfully applied to
analysis of 1998 and 1999 ATLAS tile calorimeter testbeam data, with both
input and output data stored in an object database.
