POOL Collections

The POOL Collections packages are developed and used by ATLAS.

POOL collections can be stored in both ROOT and relational formats, through the RootCollections and RelationalCollections packages, respectively. These are implemented using ROOT and CORAL directly, without passing through the POOL RootStorageSvc and RelationalStorageSvc.

The ATLAS TAG database is populated by uploading into Oracle the ROOT event collection files. For more information please refer to the ATLAS CollectionPOOLUtilitiesHowTo.
