Here you will learn how to develop an attractive, easily readable,
conceptual, business-oriented entity/relationship model, using a
variation on the UML Class Model notation. This book has two
audiences: Data modellers (both analysts and database designers)
who are convinced that UML has nothing to do with them; and UML
experts who don't realise that architectural data modelling really
is different from object modelling (and that the differences are
important). David Hay's objective is to finally bring these two
groups together in peace. Here all modellers will receive guidance
on how to produce a high quality (that is, readable)
entity/relationship model to describe the data architecture of an
organisation. The notation involved happens to be the one for class
models in the Unified Modelling Language, even though UML was
originally developed to support object-oriented design. Designers
have a different view of the world from those who develop
business-oriented conceptual data models, which means that to use
UML for architectural modelling requires some adjustments. These
adjustments are described in this book. David Hay is the author of
"Enterprise Model Patterns: Describing the World", a comprehensive
model of a generic enterprise. The diagrams were at various levels
of abstraction, and they were all rendered in the slightly modified
version of UML Class Diagrams presented here. This book is a
handbook to describe how to build models such as these. By way of
background, an appendix provides a history of the two groups,
revealing the sources of their different attitudes towards the
system development process.
