The core idea of this book is that object- oriented technology is a generic technology whose
various technical aspects can be presented in a unified and consistent framework. This applies
to both practical and formal aspects of object-oriented technology. Course tested in a variety
of object-oriented courses numerous examples figures and exercises are presented in each
chapter. The approach in this book is based on typed technologies and the core notions fit
mainstream object-oriented languages such as Java and C#. The book promotes object-oriented
constraints (assertions) their specification and verification. Object-oriented constraints
apply to specification and verification of object-oriented programs specification of the
object-oriented platform more advanced concurrent models database integrity constraints and
object-oriented transactions their specification and verification.
