Sponsor: Do you build complex software systems? See how NServiceBus makes it easier to design, build, and manage software systems that use message queues to achieve loose coupling. Get started for free.I just realized that it has been almost 10 years since Eric Evans wrote Domain-Driven Design: Tackling Complexity in the Heart of Software. Although it’s not new, it is still gaining awareness and is still very relevant. I’ve mentioned DDD in many of my posts so I figured I needed to provide some resources. If you are new to Domain Driven Design and want a summary instead of jumping into Eric Evans book, then Domain Driven Design Quickly is for you. Produced by InfoQ.com, this cliff notes book provide introductions to all the fundamentals of DDD. DDD Quickly can be downloaded free from InfoQ. Also, while browsing InfoQ, I found an older video of Eric Evans discussing what he has learned since he wrote the book. It’s a tad old, but still provides great insight.
