An Architecture and Two New Research Problems in ARCS Databases

Databases have been mandated as the chosen platform to develop automated control systems for environments where the state of the system changes rapidly, and actions need to be taken with timing constraints, such as stock trading, air traffic control, network management and process control to name a few. Such databases require the amalgamation of real-time, active and temporal characteristics. These systems have been termed ARCS. In this paper we specify an extensible architecture for ARCS like systems and identify two problems that need special attention. University of Arizona, Tucson, AZ 85721 y University of Florida, Gainesville, FL 1 Introduction Database systems that attempt to model and control external environments have attracted the attention of researchers in recent times. The application domains for such databases are numerous -- financial trading, network management, manufacturing process control, air traffic control, intelligent highway systems to name a few [2, 11, 1..
