What is BaBar Import/Export Tools

Chapter 22
Handbook of Research on Grid Technologies and Utility Computing: Concepts for Managing Large-Scale Applications
The main tasks the BaBar collaboration carries out at remote sites are the event reconstruction, the simulation production and the physics data analysis. Despite the fact that each duty needs to access a different data type and database metadata information, only one import/export software suite is shared between all the site managers.

Abstract
The BaBar experiment uses data since 1999 in examining the violation of charge and parity (CP) symmetry in the field of high energy physics. This event simulation experiment is a compute intensive task due to the complexity of the Monte-Carlo simulation implemented on the GEANT engine. Data needed as input for the simulation (stored in the ROOT format), are classified into two categories: conditions data for describing the detector status when data are recorded, and background triggers data for noise signal necessary to obtain a realistic simulation. In this chapter, the grid approach is applied to the BaBar production framework using the INFN-GRID network.
