Abstract

The Data Quality Segment Database (DQSEGDB) software is a database service, backend application programming interface (API), frontend graphical web interface, and client package used by the Laser Interferometer Gravitational-Wave Observatory, Virgo, GEO600 and the Kamioka Gravitational Wave Detector for storing and accessing metadata describing the status of their detectors. The DQSEGDB has been used in the analysis of all published detections of gravitational waves in the advanced detector era. The DQSEGDB currently stores roughly 600 million metadata entries and responds to roughly 600,000 queries per day with an average response time of 0.317 s.
