We describe a proof of concept system for analyzing high energy physics (HEP) data using database computing. The system is designed to scale up to the size required for high energy physics experiments at the Supercon-ducting SuperCollider (SSC) laboratory. These experiments will require collecting and analyzing approximately 10 to 100 million "events " per year during proton colliding beam collisions. Each "event " consists of a set of vectors with a total length of approximately one megabyte. This repre-sents an increase of approximately 2-3 orders of magnitude in the amount of data accumulated by present large I-IEP experiments. The system is called the HEPDPC System (High Energy Physics Database Computing System). At present, the Mark 0 HEPDBC System is completed, and can produce analysis of HEP experimental data approximately an order of magnitude faster than current production software on data sets of ap-proximately 1 GB. The Mark 1 HEPDBC System is currently undergoing testing and is designed to analyze data sets 10 to 100 times larger. 1
