%X In this paper we explore the design of a database machine
   that is already being implemented using T series transputers
   to determine the benefits of using the T9000 series
   transputer togeher eith its associated routing chip, the
   C104, and occam91. The language occam91, a superset of
   occam2, contains language features that directly support the
   exploitation of hardware features that have been
   incorporated into the T9000 transputer. We briefly introduce
   the underlying design of the database machine. The way in
   which the C104 routing chips can be used is then described
   in conjunction with a planar approach to the interconnection
   of nodes in the machine. Finally, we give fragments of
   occam91 that demonstrated how its features can be used in
   two different parts of the database machine. The first
   application considers the problems of allocating resources
   to a user query and the second looks at how recovery
   features can be specified.
