Object oriented data analysis in ALEPH

TL;DR

This paper discusses converting ALEPH experiment data from Fortran to C++ objects, storing it in an object-oriented database, and developing an analysis program to facilitate data analysis in high-energy physics.

Contribution

It presents the process of transitioning from traditional data structures to object-oriented data management and analysis tools within the ALEPH collaboration.

Findings

Data successfully converted from Fortran to C++ objects

Data stored in Objectivity/DB database system

Preliminary analysis program developed

Abstract

This article describes the status of the ALPHA^{++} project of the ALEPH collaboration. The ALEPH data have been converted from Fortran data structures (BOS banks) into C^{++} objects and stored in a object oriented database (Objectivity/DB), using tools provided by the RD45 collaboration and the LHC^{++} software project at CERN. A description of the database setup and of a preliminary version of an object oriented analysis program is given.
