Discussion of Domain Oriented Web Application Development Based on Grails

探讨了企业级web应用程序设计中"面向领域"的系统设计方法,对业务层的分析设计进行了研究。阐述了领域的概念,以及领域层对象的分类,对象的生命期。对Fowler提出的四种实体对象设计模型进行了比较分析。在此基础上,引入介绍类ROR的Grails应用框架的思想、概念和结构,通过一个案例,对使用Grails进行面向领域设计和实现进行阐述,为采用Grails和面向领域设计与开发提供参考。

Domain oriented in enterprise web application development is discussed, and analysis and design of business tier are focused on. Domain Concept, objects in domain tier and their life cycle is introduced. Four design model that Fowler proposed are compared.
