Enhance Reusability with Application-level Software Components

This study proposes a component design method based on an application-level component granularity model. The component functional scope is enlarged to cover an overall and standalone use case, and a descriptive language is equipped to straightforwardly express the object requirements. Necessary structural elements and interactive interfaces are combined into the model, jointly providing expanding and assembling mechanism. A collection of prototype components is generalized from common business aspects in extensive application environments, and is mapped into a suite of UI patterns and calculation patterns. The prototype components are launched into domain-oriented system development practice for evaluation.
