최근 멀티미디어 콘텐츠의 영향력이 점차 커지면서, 자신이 소유한 모바일 디바이스를 통해 멀티미디어 서비스를 제공받고자 하는 사용자의 요구가 증가되고 있다. 본 논문에서는 향후 홈 네트워크 시스템에 제공될 모바일 멀티미디어 서비스를 위한 데이타베이스 설계기법을 제안한다. 이를 위해 먼저, 서비스 운용 시 요구되는 에트리뷰트들을 추출하여 릴레이션을 구축하고 데이타베이스를 디자인한다. 특히, 데이타베이스 운영 시 발생할 수 있는 중복이나 갱신이상 현상을 막기 위하여, 릴레이션에 존재하는 다치 종속성(MVD, MultiValued Dependency)을 밝혀내고 정규화(Normal Form) 이론에 기반 한 데이타베이스를 디자인을 제안한다. 실험에서는 다양한 정규형을 만족하는 분할된 릴레이션의 질의 수행결과를 통해, 데이타 중복현상과 갱신이상의 발생을 비교, 분석함으로써, 제안한 방법이 효율적임을 입증한다.
