이질적이며, 분산되어 있는 정보 저장소들을 통합하여 가상 데이터베이스를 제공하는 미디에이터 기반 정보 통합 기술에서는 통합되는 정보의 의미 보존을 제공하는 공통 자료 모델과 이질 자료 모델 통합시 발생하는 충돌 해결 방법이 중요하므로 이에 대한 다양한 연구가 수행되고 있다. 본 논문에서는 XML Schema, XQuery 등 주요 XML 기술을 활용하여 통합되는 정보의 의미 손실을 최소화하고, 통합 자료 모델들간의 충돌 해결 표현이 용이하도록 설계한 DataBlender 시스템에 대하여 제안한다. 또한 DataBlender 시스템은 모바일 환경을 고려하여 이동 단말기에서도 통합 검색 서비스를 활용할 수 있도록 설계함으로써 차세대 인터넷 비즈니스 환경 구축의 기반이 된다.
