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." }
