데이터 웨어하우스를 이용한 임원정보시스템 구축용 아키텍쳐

Abstract

Executive information system (EIS) is a computer-based information system that supports decision makings and management activities for senior executives. Data warehouse is a database that receives data copies from legacy systems and external data sources. Data warehouse is typically optimized for decision supports and can be an attractive solution for EIS implementation. This paper proposes an architecture for implementing EIS by the use of data warehouse. The architecture consists of ten implementation layers. Interrelationships among these layers are investigated for an effective EIS implementation. An EIS prototype for a real-life enterprise is implemeneted to demonstrate the usefulness of the proposed architecture.
