媒体评论
这本书应该出现在每个软件开发人员的书架上。
——Kent Beck，软件开发方法学的泰斗，极限编程的创始人
Eric的这本书太棒太神奇了，他准确地告诉你如何让软件设计满足你理想中的模型需求。……本书读起来趣味无穷，Eric有许多有趣的故事，而且描述起来很有一套。它出版后将成为软件开发人员必读的经典之作。
——Ralph Johnson，《设计模式》的作者
如果你认为自己在面向对象编程中的投资没有收到回报，那么读了本书你就会知道自己漏掉了什么。
——Ward Cunningham， 设计模式和敏捷软件方法的先驱
Eric Evans力证作为开发核心的领域模型的重要性，他搭建了一个稳固的框架并提供了一套实现技术和技巧。这里沉淀下来的是亘古不变的智慧，在应时的方法论都沦为明日黄花后，它依然光华璀璨。
——Dave Collins，Designing Object-Oriented User Interfaces的作者
Eric完全从实战者的角度着笔，描述了无处不用的语言、与用户共享模型的好处、对象生命周期的管理、深度重构的过程和结果，这是对我们这个领域的巨大贡献。
——Luke Hohmann，Beyond Software Architecture的作者
