Separation of Analysis & Design wrt. Abstraction
Summing up separation of concerns of analysis and design wrt. abstraction, inspired by: Turner (2018) Computational Artifacts. Continue reading
A New Account of Abstraction?
Software engineering could benefit from a more rigorous grounding in epistemology, e.g., for the account of abstraction. So, let’s see what we can learn from: Raymond Turner (2018) Computational Artifacts Continue reading

A simple relational Model
Modelling foundations: What does a simple diagram ‘thing – relation – thing’ say, in terms of logic? Continue reading
Categories of semantic Models by Stachowiak
Categorisation by example of semantic models, i.e. models as we use them in software engineering etc, according to Herbert Stachowiak. Continue reading

Unambiguous Requirements Models
We’ll see that the concept of ambiguity of (requirements in software engineering) models comprises structural as well as material aspects, on all model levels (top to bottom). Continue reading
Stachowiak on semantic Requirements Modelling
Excerpt of Herbert Stachowiak’s “Allgemeine Modelltheorie” (General Model Theory). Although this is on empirical-scientific models, it provides a foundation of semantic requirements modelling. Continue reading

Splitting the Requirements Atom
Atomicity is considered an important property of requirements. However, if we take a deeper look, we see the concept of atomicity lacks in rigour. Is e.g. the atomicity concept of Logic suitable here? Continue reading
What kind of Computer Science matters?
Just came across Why Computer Science Matters? by Vugranam Sreedhar. He observes a decline in real computer scientists in favour of ‘commodity programmers’. Basically, I have to (sad but true) agree here, and would like to take a closer look … Continue reading
Modeling & Abstraction at the very heart of Business Requirements Analysis
From industrial practice we know a BA definitely adds a lot of value to an IT project. So, now we try to conceptualise this in contrast to the Biz Engineer’s and IT Architect’s role. As we’ll see, a BA’s special benefit is mainly based on abstraction (and thus modeling). Continue reading
