Database Design for Information Retrieval by Raya Fidel Pdf
Developing a database involves four distinct functions, each building on the previous ones: analysis, design, coding, and testing. In the analysis stage, the database designer defines what a database should do to make it most useful to potential users by studying user needs, or data requirements analysis, and documentation. During design, a process that defines how a database will perform its tasks, the designer concentrates on software and hardware considerations. Coding is the actual implementation of the design. Testing is carried out before full-scale installation to examine how well it will perform. This book is about analysis, explaining how to perform data requirements analysis and how to represent the outcome of this analysis in a formal and comprehensive model that is useful for software and hardware considerations. This book is suitable as a textbook or as a handbook for systems analysts, end users, or information specialists.
