摘要
领域模型是领域知识的一种图形化表示形式,是领域知识各组成部分的抽象。通过对5种领域模型的讨论,展示了不同角度和不同层次的领域知识,这些不同层次的领域知识对于认识领域内的各相关系统的特征和行为是十分有用的。此外,通过对领域知识的UML建模,提高了领域内系统的软件重用层次,以便在面向对象的软件开发过程中获得最佳的软件重用时机。
Domain models represent graphical presentation of domain knowledge and derive from the parts of domain. Five kinds of domain models are disscussed and showed domain knowledge in different levels, which is helpful to recognize the characteristics and the behaviors of dependent systems in domain. Moreover, the system's software reuse level is improved in domain by modeling the domain knowledge.
