DDD Europe is the world’s leading Domain-Driven Design conference, held every year at the end of January or early February in Theater ‘De Meervaart’ in Amsterdam, Netherlands. This year marked the 5th edition of the conference. The main conference is 2 days and was held in the first week of February. However, this is not the only thing the event has to offer. Last year they had a DDD Foundations pre-conference day. Apparently, this was such a success, that this year they did it again and added a second double-packed pre-conference day where you could learn all about Event Sourcing.
