Enhancing the Component Reusability in Data-Intensive Business Programs through Interface Separation

Visual development environments have provided good support in the reuse of graphical user interface, report and query generation, and simpler database retrieval and updating. However, many commonly used components for computation and database processing and updating are still required to be repeatedly designed and developed. The main problem is that current methods do not support the separation of component interface from a component. Component Interface is not an intrinsic property of the component. Incorporating it into the component affects the reusability of the component adversely. A program representation is proposed in this paper to address the problem. The representation enhances the reusability of a component through separating the component interface from the component.
