The effective operation of free enterprise in creating the envisioned information service industry is dependent upon three accomplishments: (1) the restructuring of our information processing industry so that a clear division of costs is mode among computing, communications, and the development of information services; (2) the wide use of multiaccess system concepts so that information services may share in the use of computer installations and so that the cost of their construction is reasonable; and (3) the development of public, message-switched communications services so that adequate provisions are made for Information security.

The possibility of holding the data collected from the plant in a functionally distributed data base is one of the interesting possibilities offered by distributed computer control systems. In the paper, the concept of state information is clarified and a new definition is given for the validity and consistency of state values in real-time sensor-based systems. A real-time distributed algorithm for establishing a valid and consistent distributed representation of the data collected from sensors by periodic sampling is presented.
