Title : The LCG POOL Project
Authors : Dirk Duellmann for the LCG POOL Project
Abstract : 
The POOL project is developing a common object storage framework for the
LHC Computing Grid (LCG) application area. POOL is tasked to store
experiment data and meta data in the multi petabyte area in a
distributed and grid enabled way. 
The project follows a hybrid approach combining C++ Object streaming
technology such as Root I/O for the bulk data with transactionally safe
relational database such as MySQL. POOL follows a strict component
approach and provides navigational access to distributed data without
exposing details of the particular storage technology. The POOL software
has been integrated into several experiment frameworks and is expected
to be used in several larger production activites by the time of the
conference.
This presentation will describe the goals of the project, the system
architecture and the interaction between main POOL components. We will
also summarise the first experience gained from experiment production
activities with POOL during this year.
