정보시스템 구조개편을 위한 DB통합기준 모델 연구

Abstract

As various business processes were performed using computers, many information systems are being built. As the number of information systems increase, the structure of information systems has become very complex, such as using linkage technologies for data linkage between systems. With the development of HW and DB SW technology, the capacity that can be processed by one DB is increased, and the information system structure is being reorganized efficiently by constructing the existing distributed DB as a single integrated DB. Since there is no model to make a decision on DB integration, an integrated standard model that can be used to establish an integration plan for many information systems is needed. In this study, the reference model identifies candidates for integration by classifying systems with high data dependency by calculating the data coupling degree proposed in this study. Through the use of the integrated reference model, DB integration targets can be quickly identified and utilized for information system restructuring.
