DDD with Ruby on Rails and MongoDB

Schedule

  • 6:30pm - 7pm Food and conversation
  • 7pm - Announcements
  • 7:10pm - Main Presentation: Paul Rayner on Domain-Driven Design (DDD) with Ruby on Rails and MongoDB
  • ~8:30pm - Close (join us for drinks afterwards)

DDD with Ruby on Rails and MongoDB

Ruby has a rich OSS ecosystem, a vibrant agile development community, a strong commitment to design, and many talented modelers and designers. Yet using DDD to do strategic design and domain modeling is virtually unknown in the Ruby community.

This presentation is an attempt to bridge the gap via an exploration of what DDD might look like through Ruby/NoSQL-coloured glasses. The basis for this will be a port of the DDD sample app to Ruby on Rails using MongoDB for persistence. We'll cover interesting questions such as:

  • How does the choice of Ruby affect the implementation of the DDD building block patterns?
  • How well does an opinionated MVC framework like Rails support doing DDD?
  • What are implications of choosing a document store like MongoDB for aggregate design and eventual consistency?

In the process we'll highlight significant lessons learned from porting the DDD sample app to Ruby/MongoDB, some significant concerns and aim to show potential ways forward.

This presentation will be an early version of the presentation I will be giving on June 14 at the DDD Exchange 2013 in London.

    Thanks to everyone who came for the great participation and feedback on the presentation, and for those who joined us for drinks at Wynkoop afterwards. It was a great night!

    The sample app is at https://github.com/paulrayner/ddd_sample_app_ruby and I've posted the slides online at http://virtual-genius.com/presentations/ddd_with_ruby_20130613.html.

    Contributors welcome. Please help me succeed in this crazy goal to have an app ready to show off at the DDD Exchange in London on June 14!

    Very informative on both DDD in general, and it's application in Ruby. Well done!
