Logics for Conceptual Data Modelling: A Review

Authors: Pablo R. Fillottrani and C. Maria Keet

Published in: TGDK, Volume 2, Issue 1 (2024): Special Issue on Trends in Graph Data and Knowledge - Part 2. Transactions on Graph Data and Knowledge, Volume 2, Issue 1

Abstract

Information modelling for databases and object-oriented information systems avails of conceptual data modelling languages such as EER and UML Class Diagrams. Many attempts exist to add logical rigour to them, for various reasons and with disparate strengths. In this paper we aim to provide a structured overview of the many efforts. We focus on aims, approaches to the formalisation, including key dimensions of choice points, popular logics used, and the main relevant reasoning services. We close with current challenges and research directions.

Composing Personalised Services on top of Abstract State Services

Authors: Hui Ma, Klaus-Dieter Schewe, Bernhard Thalheim, and Qing Wang

Published in: Dagstuhl Seminar Proceedings, Volume 8181, The Evolution of Conceptual Modeling (2008)

Abstract

We introduce Abstract State Services (ASSs) as an abstraction of data-intensive services that can be made available for use by other systems, e.g. via the web. An ASS combines a hidden database layer with an operation-equipped view layer, and can be anything from a simple function to a full-fledged Web Information System or a Data Warehouse. We adopt the fundamental approach of Abstract State Machines to model ASSs. Then we show how tailored services can be extracted from available ASSs, integrated with other ASSs and personalised to user preferences.
