               ARPA Network Data Management Working Group


   The meeting had two different phases.  The first included
   presentations of applications of networks and development work in the
   design to allow data sharing in a computer network, the second was a
   working meeting in which was discussed what the data management
   working group should do.

Phase I

   JOHN SENIOR, Univ. of Penn. and National Board of Medical Examiners,
   Phila., PA., described the use of a network to provide access to
   models that simulate medical behavior of patients.  These models are
   used primarily for teaching and testing physicians.  The network
   provides an interface by which varieties of terminals can connect to
   and access these models.  Other data bases exist to which access
   through a network may be desirable; however, these data bases have a
   "polyglot" of organizations making it presently impossible to use
   foreign data bases.

   HECTOR MAYNEZ, National Library of Medicine, described the MEDLINE
   system.  This has 1000 journals on-line to which access can be made
   via a network.  This network, as the one above, provides the
   interface for access by various terminals.  In this network are four
   or five computers with other applications such as CAI, clinical
   diagnosis, etc.

   RAY BEVERIDGE, MITRE, presented the requirements for the WWMCCS
   (World Wide Military Command and Control System) Network.  This
   network will contain 25 nodes and have a data exchange rate of the
   order of 10,000,000 characters per day.  Three type of data were
   formulated - query data with response on the order of seconds, daily
   exchange for updates and reports, and other data for weekly, monthly
   or as required reports.

   ERICA PEREZ, MITRE, discussed data management for the WWMCCS Network.
   The two problems are determining the location of desired data, and
   providing the proper security and reliability for vital data.  The
   location of data bases will be indicated in directories which may
   automatically determine which segment is applicable to a query.  The
   directory will contain lists of data bases, files users and programs.
