It is crucial for information systems engineers at all levels to understand the practice and relevant theory associated with databases. However, existing books tend to treat database issues in isolation. By presenting the reader with a coherent treatment of database material within a sound engineering context, the author prepares both the student and practitioner for the relevant roles the discipline demands. The book covers the principles and practice of database system development and management from the perspective of the development process as an engineering discipline, within the broader context of information systems. The result is a comprehensive and practical methodology for database system development that will be invaluable to students and practicing system developers.
