Hi Chien, Thank for sharing your knowledge. Personally, I think the subject is pretty abstract. But at some point, it needs to get tangible. (Identify the bounded contexts in the domain(s), write code, and so forth..) My question is: Do you have a proper example of an implementation of DDD/CQRS/Event Sourcing? And since identifying the bounded contexts has quite an impact on how things are built, how would you identify the bounded contexts in the domain? Looking forward to your response! Cheers!
