The development of Web technologies has accelerated the offer of (commercial) e-learning platforms. This paper is a first step toward the design and implementation of a platform called LeVin-Qam whose main functionalities are: (a) the provision and management of a series of exercises and tests (authoring tools); (b) a personalized navigation through the(More)
The design of Object Based Systems, which map object-oriented, semantic or knowledge representation models to an underlying database kernel system, in order to close the gap between application and database system, are currently considered as candidates for future database architectures. KRISYS (University of Kai-serslautern) and COCOON (ETH Zürich), as two(More)
—Academia and industry are increasingly concerned with producing general-purpose model composition techniques to support many software engineering activities, e.g., evolving UML design models or reconciling conflicting models. However, the current techniques fail to provide flexible and reusable architectures, a comprehensive understanding of the critical(More)
