This paper presents a framework for architecture alignment that can be positioned between approaches for software architecture, which concern software artefacts only, and strategic alignment models, which have a business focus. The framework is curre

The paper describes the methodology used in the design of a complex object server application for the Amoeba distributed operating system. It uses the top-down design that was suggested by Parnas, in which a model is turned into an implementation by

The selection of an efficient physical schema is an NP-complete problem. In this paper, we show that crucial parts of physical database design can be smoothly modelled as a Dempster-Shafer application. We exploit the properties of the Dempster-Shafer
