The Ubiquitous Language

domaindriven.be – DDD basics

Talking different languages makes projects fail.

When a customer moves, I want to send him an email.

I’ll use a micro ORM to update the database. I think I read something about a fluent SMTP library too...

Users don’t use your software to modify records in a database.

Translations are error prone.Things go lost in translation.

Projects don’t need translations, they need a shared language.

The ubiquitous language is much needed common ground that

enables learning and communication.

The model is the backbone of our shared language.

Code can’t lie, documents can.

Well-written code can capture the language as good as any document

Documents have a supporting function.

Keep a focused set of documents and be agressive about keeping them consistent.

Visualizations are awesome, but they are volatile, used to communicate ideas. Trying to

keep them updated will constrain you.

Easier said than done...

- @ToJans

Cultivating an ubiquitous language is not trivial.

But might be worth it...Communication and learning is

just so damn important.
