Abstract
An object-relationship diagrammatic technique for communicating
object-oriented database definitions is proposed and analysed. The
technique permits diagrammatic display of objects in terms of system
generated object identifiers, simple attributes, collection attributes,
and both simple and collection reference attributes. Object-relationship
diagrams are meant for final database designs with the OO approach, and
are not intended to replace the entity-relationship diagrams commonly
used in the early stages of database design. They are intended mainly
for ease of communication of complex database structure--particularly
the inherently complex relationship aspects of object-oriented database
structure--to programmers and others involved in using OO databases.
