Information and Data Modelling (Information Systems Series (McGraw-Hill Publishing Co., Inc.).) - Softcover

Inhaltsangabe

This is a completely revised version of David Benyon's unique text on database design. New chapters are included on SQL (the standard relational database language) and on object-oriented techniques for information systems design. Other material has been re-organised into sixteen chapters - each focusing on an important topic in database development.
Information and Data Modelling (second edition) begins by considering the nature of information, how it can be produced from data and how it can be managed effectively. It then presents the main modelling methods for information systems, including all the main representations used in the structured methods of analysis and design, placing these alongside the models used in object-oriented systems. After introducing the relational model, SQL is used to illustrate how relational databases can be manipulated. Techniques for designing fully normalised relations are presented before the text deals in detail with the entity-relationship (E-R) model - a graphically-based technique for database design. Chapter 15 shows how the various models can be used together to represent the information requirements of an organisation.
This book is ideally suited for a first- or second-year course on data modelling for business studies, management and computing students.
