The Organization and Management of Persistent Objects in a Multi-level Storage Architecture

摘要

With the development of large-scale application systems such as digital libraries and data warehouses, there is an increasing consensus amongst database researchers regarding the need of a database controlled tertiary storage devices for storing massive amount of data. This requirement demands to rethink the database storage management architecture and corresponding management techniques in order to efficiently organize and process these data. This paper is a summary of our studies towards this direction. It includes a proposal for a generalized multi-level storage architecture for persistent objects. Problems about the organization and managmenet of these data objects in the multi-level storage architecture are identified, and their possible solutions are discussed. The resulting techniques in this paper will be used in a multi-level storage object manager.
