Reihe: IFAC Workshop Series

The problems surrounding the subject of distributed databases in real-time control were addressed at the workshop. The difficulties included finding new, high-level conceptual models as conventional solutions are rendered useless in distributed databases. The other problems covered include the difficulties faced due to huge transaction fluxes and time constraints. The papers cover these theoretical issues plus an applications section which provides case studies of efficient applied systems which will be important for the development of this essential field.
