How This Book Should Be Used

Part 1 of this book explains how OCL can be put to use. Anyone unfamiliar with OCL should read this part. It provides an introduction to the Model Driven Architecture and the key role OCL plays in that framework. In this part, OCL is explained in a relatively informal way, mostly by example. It also offers hints and tips on how to build models using OCL, and how to implement these models.

Part 2 constitutes a reference guide that describes the OCL language completely. If you are already familiar with OCL, you can find everything you want to know about the new version of OCL in this part.

Appendix A is a reference on the terminology used in this book. Appendix B is a reference on the syntax of the language. Finally, Appendix C would be of interest to people who feel that the official (concrete) syntax of OCL could be improved. It offers an example of a different syntax, called Business Modeling Syntax, that may be substituted for the official syntax.
