Book excerpt: This guide deals with the design and implementation of advanced information systems. It covers object-oriented data management systems, distributed environments, and advanced user interfaces i.e. those integrating text, pictures, video and sound. This book also focuses on migration issues involved in going from relational database management systems to object-oriented database management issues, and discusses the advantages/disadvantages of both types of systems. The authors have developed a unique Frame-Object Analysis Methodology for advanced modelling. It also shows the reader what constitutes an advanced distributed information system and how to design and implement one. The handbook will benefit database analysts, database administrators, programmers and members of technical staff interested in data models. Andeleigh is the author of UNIX SYSTEM ARCHITECTURE.
