Design of an Application Framework for Information Systems Development - Aiming at Reuse and Architectural Simplicity -

정보시스템 개발을 위한 애플리케이션 프레임웍의 설계 - 재사용과 구조적 단순화를 목적으로 -

Typical multi-tier client/server architecture includes various and complex objects scattered around the network. Those objects must be clearly identified and designed. Then, their interface must be well-defined so that the integration can be done without major difficulties. This paper presents an application framework to increase reuse and to accomplish architectural simplicity in information systems development. Each component of the architecture is identified and designed. The proposed architecture of the application framework provides the fundamental structure for developing individual functions of an information system. Resulting architectural simplicity achieves effective and efficient maintenance throughout the lifecycle of the information systems. Although the framework aims at the reuse within a project, the productivity of information systems development across projects will be greatly improved eventually. Cases are discussed to evaluate the practicality of the architecture presented.
