摘要
软件系统架构设计中,非功能需求不仅是架构师知识结构中的重要组成部分之一,也扮演了重要的角色,甚至会直接决定架构的组成。非功能需求主要分为质量属性与约束,且来自于多方。质量属性、约束和功能需求之间能相互作用,并最终在架构设计中体现。
In the design of software system architecture, non-functional requirement is not only one of the important parts of the knowledge structure of architects, but also plays an important role in the system design, and can even determine the composition of the architecture sometimes. Non-functional requirement mainly includes quality property and restriction, from various aspects. Quality property, restriction and functional requirement can interact and materialize in the architecture design finally.
