Summary

Based on an extensive research project done by the author in the United States, Britain, Germany, France, Switzerland, Sweden, and Austria from December 1999 to June 2001, Enterprise Architecture and New Generation Information Systems focuses on four main themes: Next Generation Information Technology The Likely Technologies of this Decade Enterprise Computing The Internet as the 21st Century's Answer to Merchandising While the majority of books presently available on information systems are written from the viewpoint of system analysis, programming, or common applications, this text: Brings to the reader's attention the importance of organization and infrastructure Presents a wealth of case studies to explain the need for reengineering and restructuring Details the latest advances which influence the implementation of advanced technology Written in a simple, comprehensive manner without specific prerequisites and data processing jargon, with concepts and case studies properly explained, this book addresses itself to practitioners in computer technology, telecommunications and software development, who are interested in acquiring skills through knowledge of the most advanced applications, tools, and methods, both present and coming. Enterprise Architecture and New Generation Information Systems will prove appealing to every person charged with planning, developing, applying, and delivering advanced information systems, architectural solutions, and programming products.
