Reflections on Abstractions: Joining Classification by Relationships and Properties
How does classification based on properties go together with relationship based classes? In addition to the former posting “Concepts vs Modules for Classification”, the fit of concept lattices and relationship graphs is examined in more detail. Continue reading

Reflections on Abstractions: Concepts vs Modules for Classification
A Concept (as in Formal Concept Analysis) and a Module (as in Graph Theory) both cover the notion of Classification. Although they share the same basic idea, they reveal differences in detail. Continue reading
Reflections on Abstractions in Relational Structures. The very basic Setting.
Abstractional concepts can be found in the very basics of Graph Theory and Formal Concept Analysis. They provide the basic elements of Classification, Aggregation and Generalisation for a deeper rigorous analysis of Abstractions. Continue reading

Reflections on Abstractions: Cases vs Models
We describe by simple means of basic Finite Model Theory a very important principle in software engineering: modelling properties is more expressive than just collecting cases. This, for example, is the reason why test cases can be derived from specifications but not vice versa. Continue reading

Reflections on Abstractions: Generalisation and Aggregation
Abstraction Awareness is about gaining a deeper understanding of abstraction. With basic means of Graph Theory we diff among two kinds of abstraction: abstraction wrt. generalisation and aggregation. Continue reading
Human centric Modelling
There is a modelling at the lowend, that we use every day a million times, and there is modelling at the highend with comprehensive concepts like UML, MDD etc. Both are good to have. Perhaps approaching the modelling topic from the lowend would make it easier accessible for most of the software practitioners. Continue reading

Modelling Abstraction etc in 2011
Just reviewed my Twitter timeline of 2011: … (tweets, links, and wisdoms of the year) Continue reading
Complexity Awareness is Cost Awareness
If “engineering is producing an artifact to cost”, then how can modelling contribute to it? Continue reading
Rhinos – a Modelling Theorist’s Perspective
A structure of rigurous and relevant principles are necessary and sufficient to constitute a Modelling Theory. Everything else, like processual, behavioural, ontological or linguistic considerations, is optional. Let me enlighten this position, with the help of last week’s Rhino posting: …

Software Modelling – a Rhino’s Perspectice
Got carried away by this little picture, I recently found in a tweet, and its correspondence to modelling. So I started fooling around a bit on blind spots, redundancy and how to handle it in software modelling. Continue reading
