Publisher's Synopsis
With the advent of a new generation of object-oriented (OO) databases, there have been significant advances in the theory underlying the technology. This book brings together a selection of key developments in OO databases from a number of different areas, including semantic modelling, formal data models, language design issues, object algebra and rule-based query languages. It shows how these elements may interact within an object-oriented database system and how current commercial and experimental systems fit into the picture. Both the practical and theoretical angles of the subject are covered in detail by this book. A section containing numerous case studies of current systems explores the different ways in which an OO database may be constructed, and also covers the relevant standards. The subsequent section goes on to describe the more formal and theoretical aspects of the subject, discussing semantic and formal OO data models as well as algebraic and rule-based approaches to language design. This unique approach makes it ideal as a text for theory-based courses on OO databases, or as a state-of-the-art reference for database designers.Models and Languages of Object-Oriented;GemStone? O2? ObjectStore? IllustraReaders should be familiar with the basic concepts of relational databases and their application, and with OO programming techniques.About the authors:Georg Lausen is Professor of Computer Science at the University of Freiburg and Gottfried Vossen is Professor of Computer Science at the University of M?nster, both in Germany. They have extensive experience in teaching database courses to students and practitioners. Both authors carry out research on the foundations, as well as the applications, of object-based systems in general and object-oriented database concepts in particular.Visit Addison Wesley Longman on the World Wide Web at: http://www.awl-he.com/computinghttp://www.awl.com/cseng((A-W logo))
