Since early days, software reuse has been thought as a key strategy for reducing development costs and improving quality. Recent years, software reuse has been promoted by component-based development method. However, software reuse does not reach its full potential due to lack of the trace ability between software components and business goals. Trace ability is a key factor for reusability of software components. In this paper, we propose the pattern-oriented development approach that results in a component model. Architecture is used to describe component composition, and the links between components are defined formally. Patterns are used to describe the development expertise. The trace ability between different models at different abstract levels is created as the side effect of development process of the software components. The constructed component model has rigorous semantic, which is helpful for developer or maintainer to reason about the tasks performing with the linkage.
