API will enable It should be noted that I will not be talking much about databases in this book, since the focus of this book is on Domain-Driven Design One of the main tenants of Domain-Driven Design is persistence ignorance, and therefore, while the application is being designed, as far as you and I are concerned, the data could be coming from a text file Therefore, from this point on, I will only... along came Jimmy Nilsson’s book Applying Domain-Driven Design and Patterns, and it was then that I started to see a lot more of the patterns that could be used in conjunction with the DDD concepts Jimmy tied together some of the concepts from Martin Fowler ’s excellent book Patterns of Enterprise Application Architecture and showed how they could help with good DDD design principles Jimmy also did a great...
