REUSE OF COMPONENTS IN DATA-INTENSIVE BUSINESS PROGRAMS THROUGH INTERFACE SEPARATION

More emphasis is now being put on the support for reuse of tools used in developing data-intensive business programs. They have provided goo d support for the reuse of graphical user interfaces, report and query generation, and simple database retrieval and updating. However, many commonly used components for computation and database processing are still repeatedly designed and developed. The main problem is that curr ent methods do not support the separation of component interface from a component. Component interface is not an intrinsic property of the c omponent. Incorporating it into the component affects the reusability of the component adversely. A program representation is proposed in th is paper to address the problem. (C) 1998 Elsevier Science B.V.
