During the years 2000 and 2001 the HERA machine and the H1 experiment
performed substantial luminosity upgrades. To cope with the increased demands
on data handling an effort was made to redesign and modernize the analysis
software. Main goals were to lower turn-around time for physics analysis by
providing a single framework for data storage, event selection, physics and
event display. The new object oriented analysis environment based on the RooT
framework provides a data access front-end for the new data storage scheme and
a new event display. The analysis data is stored in four different layers of
separate files. Each layer represents a different level of abstraction, i.e.
reconstruction output, physics particles, event summary information and user
specific information. Links between the layers allow correlating quantities of
different layers. Currently, this framework is used for data analyses of the
previous collected data and for standard data production of the currently
collected data.Comment: Talk from the 2003 Computing in High energy and Nuclear Physics (CHEP
