Let It Flow in Java

Waterfall at Java

As announced in my previous article, where I had introduced Flow Design, I want to show a concrete implementation in Java. The code for this example may be found on GitHub. I will follow the blog article “IODA Architecture by Example” of Ralf Westphal which made a Flow Design and implementation for the following scenario: Build an application that translates a Roman number entered by the user into an Arabic number and vice versa. It may be valuable to read his article too, to get further details. However, I will repeat his steps (sometimes a little bit shortened) for letting Continue reading Let It Flow in Java

Why is software engineering so different from all other engineering dealing with real parts? Why is the design of a software system almost not recognizable anymore in the code? I’m quite sure, software engineering can get closer to how other engineering disciplines are doing it. It is possible to make design directly recognizable in code. This blog article series is about a possible approach. Look at this block diagram about an Apple I Video Terminal: It describes in an abstract way the components the video terminal is build from and how they interact and depend on. E.g., data is flowing Continue reading Go Beyond Object Oriented Design — Let it flow!
