Increasing the flexibility of modelling tools via constraint-based specification
Philip Gray, Ray Welland · Conference of the Centre for Advanced Studies on Collaborative Research · 1999
Most commercial modelling tools provide support for customising surface features (i.e., visual and, to some extent, interactive behaviour) of a model. Although useful and simple to use, such customisation is typically very limited; for example, one cannot change the basic representation of model components. Meta-CASE tools offer the potential for much greater customisation, but at a high cost, viz., the tool must be respecified and rebuilt. We propose an approach, constraint-based specification, which combines the flexibility of current tools with the power of CASE tool builders.
