Abstract: Analysis and design for non-functional feature of software system is a weak aspect in traditional object-oriented method, it is lack of systematic modeling method. This paper presents a reflection-based analysis and design method for non-functional feature which uses reflection to separate functional and non-functional feature. As to non-functional feature, it extends UML and combines related non-functional requirement modeling method to analyse and design.

Key words: Reflection; Non-functional feature; UML

摘要： 软件系统非功能特性的分析设计一直是面向对象方法研究中的薄弱环节，缺乏系统化的建模手段。文章提出了一种基于反射的非功能特性分析设计方法，该方法利用反射思想分离功能特性和非功能特性。对于非功能特性，扩展UML 并结合相关的非功能需求建模策略对其进行分析设计。
