【摘要】 <正> 1 引言随着信息科学与技术的空前发展,出现越来越多的大规模复杂应用,如全球信息系统、地理信息系统、数字图书馆、数据仓库等。这些大规模应用系统的重要特点之一是所处理的信息是海量的,一般达到10¹⁵bytes数量级.甚至是10¹⁸bytes数量级。对这些巨量数据进行有效管理的需求使现有的信息组织方法和处理技术面临重大挑战,这些挑战主要表现在:（1）体系结构问题。现有的数据管理系统的存储体系结构是基于第二级存储设备（如磁盘）的,象光盘组、磁带库这样更多还原

【Abstract】 It is very important for such large-scale application systems as global information systems, GIS,digital libraries,data warehousing to effectively manage and manipulate the large volumes of information (more than terabytes of data).One of challenge problems is to study massive information management system and related techniques. Since the large volumes of information are mainly stored on tertiary storage devices,the study of massive information management system should focus on the following aspects. (1)the multilevel storage architecture in which the tertiary storage devices are main data media and the secondary storage devices are data cache; (2)scalable system architecture of massive information management system; (3)retrieve process techniques. This paper will deeply study and discuss the above problems.更多还原
