Proteus: Frib Configuration Database

There is need for an integrated information system that manages the data and computational-logic used by an experimental physics facility (EPF) during its design, construction, commissioning, and operation. Such a system can be used to manage design lattices, model them, run what-if scenarios, tune the beams, troubleshoot, manage calibration data, maintenance records, alignment information and quality metrics, and generate reports for funding or regulatory agencies. A critical component of such a system is the configuration database. It manages devices, their layout, measurements, alignment, calibration, signals, and inventory. In this paper we describe development of such a component. We describe its architecture, database schema, services, and graphical and programming interfaces.
