The framework under which the PHENIX data collection system operates
is presented herein. The PHENIX detector is composed of 9 major
detector systems, some of which are made up of multiple
components. The PHENIX data collection system is designed such that
all the detector systems and subcomponents can operate independently
of each other, all together as one detector system or in any
combination in between. Because of the complex and diverse nature of
this system, the Trigger, Timing and Event Building system have to be
controlled by an overall master control architecture which integrates
the independent operation of the detector systems to ensure the physics
viability of the recorded data. Furthermore, since the data collection
system operates in a distributed networking environment, the latest IT
tools were brought to bare on the problem. OO design principles, tied
together with CORBA, Java, Objectivity and Open Source solutions, were
implemented to achieve the detector master control system. A status of
the Integration work of the data collection system is further
presented, highlighting the challenges overcome in bring the detector
online into a data taking state.
