Objectives At the completion of this subject students should know a range of information modelling techniques and abstraction principles; understand the strengths and weaknesses of various information modelling techniques; be able to apply various information modelling techniques in the design and evaluation of alternative models for an information system; and recognise the applicability and limitations of using particular information modelling techniques.
Synopsis This subject provides students with an understanding of a range of information-modelling techniques. Critical comparisons are made of the various information-modelling techniques. The practical relevance of the techniques in information systems planning and development is discussed. Topics include philosophical foundations of information modelling; approaches to information modelling - fact-based modelling, extended entity-relationship modelling, advanced relational modelling; data modelling in practice - generic data models, corporate data modelling, innovation in data modelling and the data administration role.
