Findings

Successfully expanded BdbServer capabilities

Enabled extraction of deep copies of event collections

Integrated with European DataGrid infrastructure

Abstract

The adoption of Grid technology has the potential to greatly aid the BaBar experiment. BdbServer was originally designed to extract copies of data from the Objectivity/DB database at SLAC and IN2P3. With data now stored in multiple locations in a variety of data formats, we are enhancing this tool. This will enable users to extract selected deep copies of event collections and ship them to the requested site using the facilities offered by the existing Grid infrastructure. By building on the work done by various groups in BaBar, and the European DataGrid, we have successfully expanded the capabilities of the BdbServer software. This should provide a framework for future work in data distribution.
