The GIOD Project
bluerule.gif (857 bytes)

The GIOD (Globally Interconnected Object Databases) joint project between Caltech (CACR and HEP), CERN and Hewlett-Packard is addressing the data storage and access problems posed by the next generation of particle collider experiments which will start at CERN in 2005.

The data rates from the experiments' online systems will be of order 100 MBytes/sec, giving rise to a yearly accumulation of several PetaBytes of raw data. This data, together with reconstructed particle tracks and energy clusters, will be stored and accessed in a globally distributed Object Database Management System (ODBMS).

The GIOD project is investigating the scalability of commercial ODBMS, coupling the ODBMS with hierarchical storage management systems (HPSS), and developing Object Oriented analysis software in C++ and Java.

GIOD makes heavy use of the
Exemplar and HPSS systems that are managed by CACR. Paul Messina, James Patton and Roy Williams have all been closely involved as GIOD project members since the project's inception in 1997
