Variability Control of High-cohesion Domain Component Based on Feature
基于特征的领域构件高内聚控制

It's a general topic to achieve component cohesion in the research filed based on component reuse. High-co- hesion of module (component is a special module) is always an aim of software developer. There is inherent relation- ship between All, which we get software architecture and explore software evolution and modernize legacy system, and high-cohesion component decision. The relationship between domain component and feature is established based on feature track matix. Expression of domain component vector within n-dimension space based feature is represented, then a distance matrix of domain component vector, which represent the relationship within domain components, is achieved. The domain component rank cluster tree is established combine rank cluster algorithm with the distance ma- trix of domain component vector. At last, the granularity decision strategy of high-cohesion domain component is demonstrated based on the domain component rank cluster tree.
