DDD is a wonderful design pattern for anything related to Data Science, AI, ML.
#BEST DOMAIN DRIVEN DESIGN BOOK RUBY SOFTWARE#
Then, I started working as an AI Software Engineer (mix of a software engineer + devops + data scientist), and it all clicked. The room was filled with experienced Java developers with deep Enterprise Software(tm) knowledge.
I attended a few DDD meetup a few years ago, and it never quite made sense why would you engage in this kind of architecture nowadays. If DDD makes your app code more complex, you're doing something wrong. The result of all this was the creation of a core 'domain model' that captured business behavior expected of our service and most importantly, ended up significantly simplifying the rest of the application code. Bounded contexts for our internal domain - mapping external service types to our own internal representation Defining aggregates based on our required access patterns which simplified our data access Creation of repositories that shifted much of the persistence details out of the application code Enriching the domain entities with methods that matched business behavior and performed validation Enforcing business invariants inside the model classes Adopting rich value objects to represent domain concepts instead of raw strings It was a highly unsustainable approach, and one of the first thing I did was attempt to implement strategic DDD in the areas that were the most painful. No notion of aggregate roots - every entity was just accessed ad-hoc Internal service types were liberally mixed with external service types
Internal DB identifiers were fully exposed into the code model

All validation code for these types was done in application code and was fragmented throughout the code base Almost all fields were primitives (mostly strings with a few int/doubles/dates) Each model type was just a POJO with raw getters/setters for each field There was a 'domain model' in the loosest possible sense I would describe the state of the code base when I joined as an 'Anemic Domain Model' as defined by Martin Fowler When I joined, my team had been building the backend for the first version of our app for about 4 months.
No the book is a work in progress slated for publication in 2019.Seeing a lot of hate for DDD here so let me offer an alternative point of view from someone who advocated for DDD on my team.
