Abstract : This is a report on the performance of a unique User/Interface that we designed and developed for a fully self-guided, integrated information system. This system is capable of interactive information retrieval, modeling, electronic mail delivery, and distributed networking. This interface is the central controller for all man-machine and machine-machine communications of the DOE Technical Management Information System (TMIS) of the Division of Energy Storage. It is currently installed on a PDP-11/70 machine at the Lawrence Livermore National Laboratory (LLNL) using INGRES, the relational data base management system developed at the University of California, Berkeley, as the primary underlying means for data storage and retrieval. INGRES and other subservient programs are, however, invisible to the user. The TMIS META-MACHINE, Integrated Information System (IIS), simulates in software a pseudo-computer where sequential instructions are retrieved from a 5 domain database relation. These domains, consisting of the primary address, a state function type, a forwarding address, an execution string, and a functional clustering attribute, can be arranged and manipulated by the System Administrator online, in real-time, without recompilation.
