UofT Department of Computer Science Seminar Schedule for
the week of March 19th, 1984
Tuesday, March 20th, 4:00 P.M., GB244: Dr. Michael Brodie,
Computer Corporation of America, Cambridge, Mass.:
"A database approach to integrating CAD/CAM systems".
ABSTRACT: Within the design and manufacture life cycle, there are
hundreds of specialized computer systems. Generally, these
systems have massive data repositories but inadequate data
managers, use the same data in incompatible formats and do not
communicate. Hence, there are severe problems in efficiently
coordinating these systems.
Product description data (e.g., requirements, drawings, part
hierarchies, geometry, analysis, manufacturing process, administrative)
is the common thread for integration and coordination. Ideally,
a DBMS would provide means to store, manipulate and manage all
CAD/CAM data. However, current database technology does not
address such problems as: representing engineering data semantics
(e.g., parts hierarchies and geometry), version control, data
exchange and distributed processing over heterogeneous databases.
The talk will discuss how the CAD/CAM DBMS (CCDBMS) will address
the above problems. Within the CCDBMS, existing CAD/CAM systems
will continue to operate largely autonomously. THE CCDBMS will
provide a global view of all data, comprehensive version control,
and, if desired, data management facilities for CAD/CAM systems.
The key features of the CCDBMS are: a semantically rich data
model and associated languages for engineering data, a screen
oriented interface to all CCDBMS facilities, distributed
processing, spatial (geometric) access to the parts hierarchy
and version control.
