The CDF collaboration at the Fermilab Tevatron analyses proton-antiproton interactions at a center-of=mass energy of 2 TeV.during the the collider run starting this year the experiment expects to record 1 Petabyte of data and associated data samples,The Data Handling(DH) system has online and offline components.The DH offline component provides access to the stored data,to stored reconstruction output,to stored Monte-Carlo data samples,and user owned data samples.It serves more than 450 physicists of the collaboration.The extra requirements to the offline component of the Data Handling system are simplicity and convenience for users.More than 50 million events of the CDF Run II data have been already processed using this system.
