A Research of CALS Integrated Database Based on Federated Database Systems

연방 데이터베이스 시스템 기반의 CALS 통합 데이터베이스 구현 연구

CALS IDB (Integrated database) is one of core technologies that embodies the principle of a shared data environment for the life cycle related data in CALS environment. In this study, to successfully share the data, we first classified the data types employed in the CALS environment and then discussed the data heterogeneity issued in data integration processes. To effectively solve this heterogeneity, we proposed the federated database systems as a candidate system especially focusing on the major functions and core element technologies.
