Based on a data modelling course held at the Open University, this updated edition places data modelling alongside functional analysis, aiming to balance practical issues with database theory. No previous computing knowledge is assumed. It features examples and an extended case study.

Includes additional chapters on the latest version of SQL and data dictionary systems
Relates E-R modelling and relational model to other modelling methods such as object-orientation
Non technical and practical approach throughout
Many examples and an extended case study
Information and Data Modelling, 2/e 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 normalized 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 organization.
