Abstract

This article describes a proposed solution for handling take-home and disconnected user support on a host/intelligent workstation system. The main problem in supplying this level of support is the question of where the user's data files should be stored, and at what point, if at all, they should be downloaded either to a diskette for take-home work or to the intelligent workstation for disconnected support.

Briefcase Icon for Take-Home and Disconnected User Support

       This article describes a proposed solution for handling
take-home and disconnected user support on a host/intelligent
workstation system.  The main problem in supplying this level of
support is the question of where the user's data files should be
stored, and at what point, if at all, they should be downloaded
either to a diskette for take-home work or to the intelligent
workstation for disconnected support.

      Most software packages propose all-or-nothing solutions which
have substantial performance implications.  Either such disconnected
support is not available, and the user is only functional when the
host (be it LAN server or mainframe computer) is running, or the
support is provided by keeping duplicate copies of every file on both
the host and the workstation.  This raises significant questions
about data integrity, shadowing, the amount of performance sacrificed
for the feature, and so on.

      In addition, the current solutions give secretaries the same
cap abilities and performance liabilities as managers and other user
classes, not all of whom need the ability in the first place.  This
causes heavy office users who only work at their desks to pay for the
privileges which are needed only by a few who are light users of the
office, and who can stand the performance loss created by the
take-home or disconnected user solution.

      We propose that rather than making system-wide decisions about
the level of disconnected/take-home support provided for each user,
the individual should be able to determine the level of support
desired.  An icon of a briefcase will be provided for the user. (See
Fig. 1.)  When "open" for use, as in the figure, it is available to
have files or other data objects "put in it" to be taken home or
downloaded to the workstation.  This list is maintained by the user,
and may be as simple as a single file which is to be taken home
that evening or as complex as the entire six-month calendar,
