Active-Group-Chef @sperbsen und Kollege Markus Schlegel sind in der heutigen Folge des Podcasts Software Testing dabei. Reingucken oder -hören lohnt sich! https://www.richard-seidl.com/de/blog/qualitaet-formale-methoden

Ab dem 23.3. unterrichtet unser Chef Dr. Michael Sperber (@sperbsen) die iSAQB-Advanced-Level-Schulung “Funktionale Softwarearchitektur” (FUNAR), bei unseren Freunden bei oose in Hamburg.
Die FUNAR entwickeln wir seit 2019 weiter. Sie bietet ein intensives Training in Softwarearchitektur mit Daten, Funktionen, Abstraktionen und ein bißchen Mathematik - Architektur, die jedes System besser macht. Vorkenntnisse sind nicht erforderlich, eine Einführung in die funktionale Programmierung machen wir am ersten Tag.

Looking forward to yet another OOP talk. I'll talk about something the software development/architecture community seems to have lost, namely leveraging powerful data/object models to design rich applications that make our lives better. See you next Thursday!

It's been a while - but next week, we'll once again have a booth at @oop.
Come see us to chat about software architecture beyond the boring mainstream, how to have a great digital transformation project, and our diverse offering of accredited @isaqb trainings.
(Or just come to see a booth that looks ... a little different.)
Also check out our CEO Michael Sperber's talk on Resurrecting OOA/OOD for the 21st Century on Thursday!

Am 25. November 2025 ist AG-Chef @sperbsen mit seinem Vortrag "Great Software Architecture With Glorious Data Models" beim vom iSAQB und @heiseonline veranstalteten Software Architecture Gathering in Berlin:

Great Software Architecture With Glorious Data Models - Software Architecture Gathering 2025

Domain models are crucial for good software architecture: Good models are expressive and elastic in the face of changes, software projects are full of poor models that make changes pure hell. This goes especially for *data models* - the structure of the objects that make up our domain. Yet the common collaborative modeling techniques focus almost exclusively on process - what happens to domain objects, rather than their structure. The talk examines the impact of data models on software architecture, and gives an overview of effective techniques for designing them. Specifically we'll look at: - differences and commonalities between data models and process models - over-structured database models as a source of coupling and suffering - the use and abuse of mutable state - design recipes as a systematic technique for structuring data - abstraction as a tool for improving the expressiveness of data without losing the connection to the domain - combinator models as a tool for creating long-lived and flexible data models While many of the insights techniques presented come from functional programming, they are equally applicable in OO languages and projects.

New article up on our blog on functional programming: Markus Schlegel's "On the Testability of Pure Functions" talks about testability, formalisability, and the relationship between these two qualities. Read it here:

Der Blogartikel zur Testbarkeit von puren Funktionen von Kollege Markus Schlegel ist nun auch in englischer Sprache verfügbar:

Funktionale Programmierung - On the Testability of Pure Functions

Der Kollege Schlegel hat ein paar kluge Gedanken zum Thema 'Testbarkeit von puren Funktionen' und das Verhältnis von "testbar" und "formalisierbar" aufgeschrieben. Kurz und lesenswert auf unserem @activegroupgmbh Firmenblog https://funktionale-programmierung.de/2025/10/13/testbarkeit-pure-funktionen.html
