Abstract:
-
In most industrial facilities, existing control, engineering and
administrative systems operate on computer systems from many different
manufacturers and use many different data systems. They have existing
independently designed, and therefore overlapping, databases, further
complicated by logical and physical differences in the representation
of the same real- world objects from database to database. But the
most important characteristics of these systems are that they are the
data repositories for the current manufacturing enterprise, that the
existing application programs depend on them, and that the validity of
their data depends on those application programs. The ideal
integrated data system, therefore, cooperates with the existing
applications on the existing databases, while enabling new application
programs to be built which use these databases in new or improved
ways, expanding the capabilities of the enterprise, and which are
insulated from accidental distinction in data location, representation
and access mechanisms.
