The Transients Database
The Aim
◮ Store all LOFAR measurements
◮ Build light-curve catalogue
◮ Enable fast processing, and access (exploit database engine)
The Schema Design
◮ Propagate algorithms to the data
◮ Optimise for comparison of latest measurements with a
statistical model of all measurements
◮ Recently: redesign, renaming, explicit table relations, installing
& upgrading
The Content
◮ External catalogues: VLSS(r), WENSS, NVSS, exoplanets
◮ Standard frequency bands (as defined for MSSS)
◮ Original measurements
◮ Deduced data: associations between measurements,
cataloguing measurements
◮ Meta-data: pipeline configuration and task settings
