构件演化是指构件根据用户的需求和技术的变化而不断改变,它是由一系列复杂的变化活动组成的。分析了构件演化的特点及其对度量的影响,根据GQM度量定义模型,给出了构件演化过程中的主要度量。希望通过度量和测评,能够有效地对构件演化进行控制,保持构件系统的一致性和稳定性。
Component evolution refers to the shifting changes according to customer demands and technology changes, it consists of a series of complicated changing activities. In this article it analyses the characteristics of component evolution and its influence on metrics. Based on GQM model, a main metric for component evolution process is proposed. By measuring and evaluating, it hopes to effectively control the component evolution and to keep the consistency and the stability of component system.
