读书 Domain-Driven Design: Tacklin

Another lesson you'll learn from this book is that domain models aren't first modeled and then
implemented. Like many people, I've come to reject the phased thinking of "design, then build."
But the lesson of Eric's experience is that the really powerful domain models evolve over time, and
even the most experienced modelers find that they gain their best ideas after the initial releases of
a system.
