This book discusses information modelling combined with a description of the express information model specification language. EXPRESS is a new language that when used with information modelling abstracts away the implementation bias prevalent in current data modelling technology.One of the main tenets of EXPRESS is that a clear separation exists between the information model and the information system environment - a piece of information is not tied to a single application that uses it. The book will be of interest to data and information modellers in both universities and businesses, especially those concerned with object-oriented systems as it illustrates the development and use of information models using EXPRESS.

The book is well organised and well written. It is easy to find particular constructs of the language ... The book is readable and I have no hesitation to recommend it to those who want to know more about data modelling and EXPRESS, and also to those who already know the language but need an easy reference.
