One of challenge problems is to study massive information man-agement system and related techniques. Since the large volumes of information are mainly stored on ter-tiary storage devices,the study of massive information management system should focus on the follow-ing aspects. (l)the multilevel storage architecture in which the tertiary storage devices are main datamedia and the secondary storage devices are data cache; (2)scalable system architecture of massive in-formation management system; (3)retrieve process techniques. This paper will deeply study and discussthe above oroblems.展开更多
