Databases for the Pi of the Sky experiment

This paper describes databases used in the Pi of the Sky experiment, particularly the databases of stars and observations. The Pi of the Sky experiment, located at Las Campanas Observatory in Chile searches for rapidly changing optical objects such as Gamma Ray Bursts (GRB). The system consists of two CCD cameras placed on paralactic mount and operated by a PC, equipped with dedicated software. The data acquired is reduced and mainly the brightness of stars is stored in the database. A web interface for the database has been created. It allows easy and quick access to the experiment’s data and to other star catalogs, which are also included in our databases
