| Abstract |
The H1 experiment at HERA is undertaking a major upgrade of its analysis software. The new integrated object-oriented physics analysis framework comprises a new data storage scheme, a data access front-end, and a new event display. The analysis data is stored in three separate layers, containing reconstruction, particle 4-vector, and event-summary information. The event-summary especially facilitates a fast selection of events based on event classification and kinematics. At particle level a custom-built pointer relation allows for direct access from the particle 4-vectors to the corresponding track and cluster information which is stored at reconstruction level. The user access to the data files is encapsulated using extensions to the RooT tree class in connection with a mySQL database. First results and benchmarks will be presented. |
