Knowledge databases in control systems

The modern industrial age urges the software industry to help them benefit from knowledge systems, which, besides filtering out an information flood, might initiate appropriate actions in response to process changes. These could be achieved through active objects. An active object is autonomous: the privilege of such an object is its capability of initialing actions of its own, very intriguing feature for control systems. Java, notably prominent object-oriented programming language supports concurrency, and to some extent soft real-timeness. This paper focuses on active object-oriented databases applied to an industrial application
