Case Method Avis

"It was a pleasure to write the Foreword for such a well-written, informative book ( Case Method: Entity Relationship Modelling ), I learned some new guidelines for entity relationship modelling when I read it over." - Dr Carma McClure, Vice President of Research, Extended Intelligence Inc. "Richard Barker has managed to encapsulate in book form ( Case Method: Entity Relationship Modelling ) his many years of data modelling theory and practice. His new book comfortably achieves the seemingly impossible task of being both introductory and definitive at one and the same time." - Russell Jones, Editor, Software Development Monitor
