Rebuilding With DDD



This presentation explores how the platform driving the, (3 time winner of the 'Best Newspaper' Webby), site was almost completely rebuilt using the principles of DDD. Key evolutions of our model, how DDD encouraged domain experts to greater iinvolvement, and how we maintained a deep, malleable domain model, whilst meeting deadlines are also discussed.


Phil Wills is a physicist and frustrated astronaut that opted for the next best thing: a career in software development for the web. Phil has experience with a broad range of languages and technologies, but has spent the past three years focussing on redeveloping with a focus on building a strong domain model and achieving high performance.

  • Database versioning

    Phil mentions a solution on database versioning, but does not tell much about it as "it was presented yesterday by ... in a talk about issues to do with continuous integration deployment." Perhaps this talk was recorded and there is a link to it? Would love to watch it.

    Hi Dandik,

    I was referring primarily to dbdeploy. It's a simple approach that works as long as you keep to the discipline of only make structural changes to your database using it.

    If you want to capture the current state for a baseline, but don't want the whole mass of your production data, then you might be interested in the recently open-sourced databaseliner. It's not as mature as dbdeploy, but we've been using it succesfully on our schema, which is definitely non-trivial.

    I'm afraid I didn't really prepare the presentation for an audience watching it on the web, so will try and keep an eye on here to clear up any other confusion.
