Overview

Scott Wlaschin's NDC talk on using statically typed functional programming, F# in particular, to model a business domain. Types are used to represent the domain precisely and to encode business rules so that illegal states cannot be built, with the compiler acting as an instant unit test.

On Hacker News

HN people recommend it as an eye-opening talk whose domain-modeling ideas carry over to other languages and make a strong compiler feel like a coding partner.

If anyone is looking for a really eye-opening video take a look at that this. "Domain Modeling Made Functional" It's applying Functional Programming to plain old Enterprise line of business apps in F#. The author argues why it's so much simpler, and simply walks through an example with cases. It's hard not to be persuaded. It leaves behind all of the lofty crazy maths you see in a lot of presentations of FP, and just shows how it's a simpler technique to solve real world problems. Domain Modeling Made Functional - [VIDEO] (Watch on 1.25x speed) It's really impressive, and also surprising why more people promoting FP don't show it's tangible benefits and simplicity vs. the theoretical/abstract way it's usually presented. It's also a great introduction to 'Domain Driven Design' and data modeling regardless of the language you use.

The "F# for fun and profit" site by Scott Wlaschin is a great jumping-off point: [LINK] I discovered it when I was reading a lot about domain driven design, and I stumbled upon a talk by the author that kind of blew my mind: "Domain Modeling Made Functional" [VIDEO]

I adore Scott Wlaschin's work [0] -- that's where I picked up on the acronym, BLOBS! F# is super cool, I agree. [0] [VIDEO]
