This unique book shows how ORN can be used in UML class diagrams and database definition languages (DDLs). This will allow the reader to better model and implement relationships and thus more productively develop database applications.
From the reviews:
“This book provides a comprehensive reference for Object Relationship Notation (ORN), a declarative extension that adds referential actions to UML multiplicities for the conceptual modeling of relationships in database applications. The book is intended as a text for a broad audience including researchers, developers of DBMSs and data modeling tools, database practitioners, and students. ... Throughout this book many examples are provided and allow for a very good understanding of the covered material. ... To summarize, I recommend this book as a reference for ORN.” (Gottfried Vossen, Zentralblatt MATH, Vol. 1185, 2010)
