Mit Event Sourcing verdrängt endlich Konstruktivismus den bisherigen Materialismus des immer noch dominierenden RDBMS/OO-Denkens.1 Und ich halte…

CQS (Command Query Separation) is a well known principle for disentangling method responsibilities in OO software. I had known it for quite some time, but only recently actually have taken it to heart. And now I’m really loving it. I cannot imagine doing without it.

What’s Event Sourcing (ES) for? Why deviate from the all encompassing cosy domain data models for keeping and storing application state? Why jump through all the hoops of ES and risk overengineered code? The other day I read an article about Event Sourcing by Tobias…

Developers shun it, if they can: Eventual Consistency (EC). Rather they jump through hoops and invest huge efforts and drive technologies through all sorts of contortions to avoid even small areas of EC in their applications. What developers love is Immediate Consistency (IC). That’s what…

As you might have guessed if you’ve followed my postings about the Sleepy Hollow Architecture and the Terminus Architecture, I’m on a quest. I want to find a better way to fundamentally structure software for higher evolvability. Not as an end to itself, but because…
