What we'll do

When you get out into the world and start modelling, you quickly realize that things can get...Well, hairy. When that happens, it might be time for a Cut & Shave. And that's what this month's speaker Herman Peeren is here to offer: a bunch of tools to slice, dice and remodel your DDD-inspired models into something looking sharper than a straight razor.

This month's talk food, drinks and space are provided by the fine folks of Holland Startup, over in the Dotslash event space. So, don't let yourself get overgrown with modelling woes: sit back, relax and slap a hot towel on your face as you talk it out!

19:00 - Doors open with food & drinks
19:30 - Welcome
19:35 - Talk: CUT & SHAVE: Domain Driven Design explained and simplified with the aid of some old philosophers.
20:25 - Raffle & News
20:30 - Social!

Main Talk: Cut & Shave
In mister Occam's barbershop we'll have Domain Modelling in our chair to have a fresh cut and shave. We'll cut, redefine, rename and rearrange concepts like bounded contexts, ubiquitous language, context maps, aggregates and their roots, entities, value objects and event sourcing. Our modelling tools have grown, but might need some maintenance service... Language is the vehicle of modelling, it is the tool by which we understand the world. Our words are the building blocks of our models. If our language is imprecise, inconsistent or contradictory, so our models will be imprecise, inconsistent or contradictory. Although some practicioners of Domain Driven Design proudly call themselves “domain linguists”, not all DDD-jargon is very well defined. Some concepts come from different paradigms or contain logical errors. Too broad or too narrow definitions introduce unnecessary accidental complexity. This presentation aims to show some mistakes and do proposals to improve the situation. The proof of the pudding is to show how models can be made more useful by that. On our road we'll be helped by some modellers from the past, like Aristotle, Hume, Kant, Wittgenstein or Ryle. And we'll see how a 14th century razor blade can still be sharp.
