This guide illustrates what constitutes an advanced distributed information system, and how to design and implement one. The author presents the key elements of an advanced distributed information system: a data management system supporting many classes of data; a distributed (networked) environment supporting LANs or WANS with one or more database servers; an advanced user interface. This book presents the authors' FRAME-OBJECT ANALYSIS METHODOLOGY for advanced modelling. This book also addresses the features of both relational and object-oriented databases with emphasis being given to techniques for object-oriented design. This book will benefit database professionals and members of technical staff interested in data modelling.
