A knowledge system consists of a balance between a pure store and a processor.
The role of object-oriented analysis is to keep the balance between data and processes
for any particular knowledge source. This balance ensures that the designer can con-
ceive of his model more easily, in the form of the object. The notion of 'Frames',
where a kind of form (a frame) is created for a generic object, was an original concep-
tion that led to object analysis. The frame has been developed from experience in the
field. The object frame therefore lacks the coherence and completeness that might
be expected had it been derived from a formal theory of a knowledge representation.

The Boundaries of Knowledge Representation
Knowledge of the world is a human and social affair. However, it does have identifi-
able elements that allow us to create hypotheses, represent knowledge and discuss the
nature of intelligence. Given such a study it is possible, within the human framework,
to attribute knowledge to inanimate objects such as computers and other machines.
