基于领域驱动设计的应用系统模型

摘要

领域驱动设计（Domain-Driven Design，DDD）是Evans提出来的用来处理软件系统核心复杂性的方法。该方法的有效性在实践中得到证明，但是方法在细节上存在不够清晰、对设计人员素质要求高等问题。在对大量业务系统进行分析和实践的基础上，对业务对象的公共操作进行了抽象，提出了基于DDD的应用系统模型来指导系统设计和开发。研发了开发框架对业务系统中通用的属性和操作进行了封装。实际项目中的应用证明了该框架能够辅助进行系统设计开发，提高软件开发效率和减少缺陷。%Domain-Driven Design(DDD)is introduced by Evans E. to track complexity in the software,which has been proved effectively in practical.However,it lacks of fine-grained definition of some details and depends on the high-quality of the developers and so on.Based on the analysis of a number of business systems,the common operations of business object are abstracted,and an application model of DDD is proposed to guide the system design and development.Meanwhile,a framework is proposed to encapsulate common properties and operations of business system.In practical,this framework has been proved to assist the soft-ware development and improve the efficiency and reduce effort.
