“…Heuristics useful for finding important sub-objects are nearby labels, objects at ends of long lines, and adjacent blank areas (Kasik, 2004). Processing can also in some applications do "visual abstraction" where, say, a rectangle is substituted for a complex part of the diagram that is known to be a conceptual unit (Egyed, 2002). http://faculty.nps.edu/ncrowe/contentrep.htm…”

Small handheld devices are increasingly popular, but it is difficult to display images, audio, and video on them as users would like. The limitations of such devices in display and processing for multimedia require significant planning to overcome. We discuss several ideas that are being studied, including panning and zooming, translation, substitution of links, and reformulation of data. Many of these require some ranking of data content, so we also discuss methods for that, as well as the process of redoing a data display. This topic is a highly active area of research, and many innovations will be appearing soon.

Abstract:Although the evolving field of software engineering introduces many methods and modelling techniques, we conjecture that the concepts of abstraction and generality are among the fundamentals of each such methodology. This study proposed a formal representation of these two concepts, along with a two-dimensional space for the representation of their application. Based on the examples, we further elaborate and discuss the notion of abstraction and generalisation transformations in various domains of software development.

“…For example, our approach transforms the low-level class diagram into a form that makes the results directly comparable with the high-level diagram. As part of our collaboration with Rational Corporation we created such an transformation technique [9] and, in this paper, we will demonstrate how its results can be used for direct, one-to-one comparison to detect inconsistencies.…”

Abstract. Software models are key in separating and solving independent development concerns. However, there is still a gap on how to transition design information among these separate, but related models during development and maintenance. This paper addresses the problem on how to maintain the consistency of UML class diagrams during various levels of refinement. We present a new approach to automated consistency checking called ViewIntegra. Our approach separates consistency checking into transformation and comparison. It uses transformation to translate model elements to simplify their subsequent comparison. Transformation-based consistency checking, in the manner we use it, is new since we use transformation to bridge the gap between software models. No intermediate models or model checkers are required; developers need only be familiar with the models they design with and none other. The separation of transformation and comparison makes our approach to consistency checking more transparent. It also makes our approach useful for both propagating design changes among models and validating consistency. This gives developers added flexibility in deciding when to re-generate a model from scratch or when to resolve its inconsistencies. Although this paper emphasizes the adaptation and evaluation of class diagrams, we found our technique to be equally useful on other models. Our approach is tool supported.
