Visual notations form an integral part of the language of software engineering (SE). Yet historically, SE researchers and notation designers have ignored or undervalued issues of visual representation. In evaluating and comparing notations, details of visual syntax are rarely discussed. In designing notations, the majority of effort is spent on semantics,(More)
Information Systems (IS) design research tends to emphasise the development of new methods (normative research), while addressing the evaluation of methods in only a limited fashion. A possible reason for this is the philosophical and methodological problems involved in validating methods (“knowledge how”) as opposed to theses (“knowledge that”). “Knowledge(More)
This paper describes a method for developing dimensional models from traditional Entity Relationship models. This can be used to design data warehouses and data marts based on enterprise data models. The first step of the method involves classifying entities in the data model into a number of categories. The second step involves identifying hierarchies that(More)
This paper describes the results of a 5-year research programme into evaluating and improving the quality of data models. The theoretical base for this work was a data model quality management framework proposed by Moody and Shanks (In: P. Loucopolous (Ed.), Proceedings of the 13th International Conference on the Entity Relationship Approach, Manchester,(More)
This paper develops a framework for evaluating the quality of data models and choosing between alternative representations of requirements. For any particular set of user requirements there are many possible models, each of which has drastically different implications for database and systems design. In the absence of formally defined and agreed criteria,(More)
There has been a great deal of debate about the status of information systems (IS) as an academic discipline, its progress, and continued survival. Most of these critiques have been rather inward-looking, and have focused either on research methodology or the need to develop theoretical foundations. This paper argues that as an applied discipline, IS will(More)
