The Solenoidal Tracker At RHIC (STAR) is a large acceptance collider
detector, commissioned at Brookhaven National Laboratory in 1999 and
anticipating first physics running in spring 2000. STAR employs a 4m
scale TPC and other detectors to measure the momentum and identify
several thousand particles per event with the foremost physics
objective being the discovery and characterization of the Quark Gluon
Plasma. STAR has developed an offline software infrastructure designed
to meet the near and long term needs of the STAR physics program. A
component based framework built over the ROOT system supports both
wrapped legacy Fortran simulation and reconstruction codes and STAR's
fully C++/OO physics analysis code, and is used both for offline
production and as a physics analysis environment. STAR's C++/OO event
model used in all physics analysis software presents a purely
transient, I/O independent interface to the user while the
implementation directly employs ROOT I/O to provide efficient and
maintainable I/O. Conditions, event store and production database
facilities have been implemented using MySQL, STAR having ceased
development of ODBMS-based databases. This paper will present a
general overview of STAR computing with particular attention to progress
with and lessons from our OO experience.
