✦ Synopsis

This paper presents the design and initial implementation of software which uses a relational database management system for storage and retrieval of real and Monte Carlo generated events from a charm and beauty spectrometer with a vertex detector. The purpose of the software is to graphically display and interactively manipulate the events, fit tracks and vertices and calculate physics quantities. The INGRES database forms the core of the system, while the D13000 graphics package is used to plot the events. The paper introduces relational database concepts and their applicability to high energy physics data. It also evaluates the environment provided by INGRES, particularly its usefulness in code development and its Fortran interface. Specifics of the database design we have chosen are detailed as well. * Work supported by the US Department of Energy under without coding changes. Hardware database mac-Contract DE-ACO2-76ER03075.
