It turns out that domain-driven design works for more than just cargo shipping. Vladik Khononov shares his experience using the domain-driven design methodology at Plexop, a large-scale marketing system that spans over a dozen of different business domains, from the management of advertising spaces to sales agents’ commissions. Vladik and his team had very limited resources and a very short time to market to implement Plexop. He explains how DDD allowed them to manage complexities, discusses different strategies for defining context boundaries, and of course, details the lessons that they learned the hard way.
