Chapter
GEA (General Enterprise Architecting) is an enterprise architecture method which has been developed and matured over the past 15 years. The GEA method has emerged out of needs from practice, and differs from other enterprise architecture approaches in that it has a strong focus on enterprise coherence and the explicit governance thereof. This focus...

The outbreak of the SARS-CoV-2 pandemic of the new COVID-19 disease (COVID-19 for short) demands empowering existing medical, economic, and social emergency backend systems with data analytics capabilities. An impediment in taking advantages of data analytics in these systems is the lack of a unified framework or reference model. Ontologies are hig...

A domain model provides an explicit knowledge representation of (selected aspects of) some domain of interest. The transition to the digital age results in an increased need for domain models that are machine understandable. We posit that, at the same time, there is an increasing need for non-experts (in modeling) to be able to create such models,...
Conference Paper
The Digital Transformation of our society requires IT infrastructures to be more agile, more adaptive, and more connected than ever. At the same time, the owners of such infrastructures are confronted with an increase in regulatory pressure (e.g., the GDPR). These developments put a lot of stress on IT management and governance. To enable IT manage...

In this paper a functionality taxonomy for document search engines is proposed. It can be used to assess the features of a search engine, to position search engines relative to each other, or to select which search engine 'fits' a certain situation. One is able to identify areas for improvement. During development, we were guided by the viewpoint o...

In this article we discuss an approach to database optimisation in which a conceptual schema is optimised by applying a sequence of transformations. By performing these optimisations on the conceptual schema, a large part of the database optimisation can be done before actually sliding down the software development waterfall. When optimising schema...

In this report the conceptual query language ConQuer-92 is introduced. This query language serves as the backbone of InfoAssistant's query facilities. Furthermore, this language can also be used for the specification of derivation rules (e.g. subtype defining rules) and textual constraints in InfoModeler. This report is solely concerned with a form...

Many of today's applications have an, almost tangible, monolithic nature. They are built as 'islands', purporting to be self contained, offering little or nothing in the way of integration with other applications. In the past, being large and self-contained may have eliminated the need to interact with other solutions to some extent. However, in th...

In the 1950’s, W. Ross Ashby introduced the Law of Requisite Variety in the context of General Systems Theory. A key concept underlying this theory is the notion of variety, defined as the total number of distinct states of a system (in the most general sense). We argue that domain modelling (including enterprise modelling) needs to confront differ...
