Abstract:

ConceptBase is an experimental deductive object base management system specifically intended for meta data management and the coordination of design environments. It integrates techniques from deductive, object-oriented, and temporal databases in the logical framework of the data model Telos. The usage environment offers an extensible palette of graphical, tabular, and textual windows conforming to the X11 standard. The communication between the windows and the object base is organized in a client-server architecture using TCP/IP.
