Information system software productivity can be increased by improving the maintainability and modifiability of the software produced. This latter in turn can be achieved by the provision of comprehensive support for views, since view support allows application programs to continue to operate unchanged when the underlying information system is modified. But, supporting views depends upon a solution...
Correct and efficient Dynamic Interactive Systems (DISs) are very difficult to conceptualize, model, implement, and maintain due to their dynamism and multiple concurrent interactive processes. As a result construction of DISs is time-consuming and implemented DISs are error-prone and difficult to comprehend and analyze. In this paper we describe an intuitive and systematic process by which models...
Information systems that are accessible via the web have become a very important class of large-scale software systems. In order to assure a high quality of such systems we propose a layered approach using integrated methods for all levels. In doing so we bring together knowledge from semiotics, goal-oriented requirements engineering, conceptual modelling, databases, human-computer interaction and...
Requirements elicitation involves the construction of large sets of conceptual models. An important step in the analysis of these models is checking their consistency. Existing research largely focuses on checking consistency of individual models and of relationships between pairs of models. However, such strategy does not guarantee global consistency. In this paper, we propose a consistency checking...
