What is DDD by Eric Evans (DDD Europe 2019)
Evans explains some of the most important concepts related to DDD while taking a critical look at how we traditionally think about models. Suggests asking "hich model would be more useful to solve this problem" instead of relying on our understanding of objects "in real world". He also emphasizes the importance of communication with domain experts an use of ubiquitous language.
