설계 및 생산 시스템 간의 데이타 교환을 위하여 국제 표준화 프로젝트인 STEP 에서는 제품 모델의 표준과 데이타 저장 시스템과의 인터페이스를 위한 응용 프로그램인 SDAI 를 정의하였다. 공학 분야의 다양한 정보 형태와 방대한 데이타를 취급하기 위하여 화일 시스템과 다양한 데이타베이스 시스템이 사용되고 있으나, 서로 다른 스키마 언어와 데이타 조작 언어로 인하여 데이타베이스 시스템의 조작과 관리가 용이하지 않다. 본 연구에서는 STEP 에서 정의한 정보 모델링 언어인 EXPRESS 를 이용하여 관계형, 객체지향형, 그리고 확장된 관계형 데이타베이스 시스템과의 인터페이스를 지원하는 다중 데이타베이스 시스템을 구현하였다. 본 논문에서는 Oracle UniSQL, 그리고 Versant 를 대상으로 데이타베이스 통합에 필요한 스키마 변환과 스키마 통합 과정 및 SDAI 의 구현 방법을 제시하였다.
