The new object oriented analysis framework for H1

Abstract : 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.
