DATABASE STORAGE SYSTEM BASED ON OPTICAL DISK LIBRARY, AND METHOD USING SAME

摘要

A database storage system based on an optical disk library comprises a server, an optical disk library, and a magnetic disk storage. The database storage system comprises a field structure generation module, a record index generation module, a storage space allocation module, a storage space state module, a record linkage module, and a record splitting module; and further comprises an optical disk library establishment and registration module, a search-term storage module, and a search-term index generation module. By means of the present invention, a database is directly established in a write-once optical disk or an optical disk of another type, and data is directly entered into the database on the optical disk; when a full-text index data file is separately stored on a disk storage or an optical disk, full-text retrieval from a database on an optical disk of the optical disk library can be performed within seconds, an original file from database files on an optical disk can be invoked within seconds, bringing the response performance of optical disk-based databases on an optical disk library close to that of online magnetic-disk storage, thereby effectively solving the technical problem of managing and accessing large-scale optical disk-based databases. Also provided is a data processing method.
