摘要:
A heterogeneous database storage system based on optical disk includes a magnetic disk storage device and an optical disk storage device connecting, via a data connection, to a server. A relational database management system, a non-relational database management system, a data processor and a database connector are installed on the server. Fields of a record are divided into two parts by the data processor. A part of the fields are in a relational database, and the other part of the fields are in a non-relational database. Fields of the relational database constitute a subrecord of the relational database, and Fields of the non-relational database constitute a subrecord of the non-relational database. The subrecord of the relation database and the corresponding subrecord of the non-relational database form an integral record by the database connector.

A database storage system based on Jukebox comprises a server, a jukebox and a magnetic disk storage. The database management system comprises a field structure generation module, a record index generation module, a storage space allocation module, a storage space status module, a record linkage module, a record split module; further comprises a database creation and input on optical disk module, a search-term storage module, a search-term index generation module. By means of the present invention, a database is directly created on a write-once optical disk or an optical disk of other types, data is input into the database on the optical disk; full-text search for the databases on the optical disks in the jukebox can be performed within seconds, an original file of a database file on an optical disk can be retrieved within seconds, solving effectively the technical problems of managing and accessing large-scale optical disks with databases.

A database dual-core storage system based on optical disk comprises a server, a magnetic disk storage device and an optical disk storage device connecting to the server via data connection, a database management system, a data processor and a data connector installed on the server, wherein the database management system is arranged for completing database management and data management of the magnetic disk storage device and the optical disk storage device in response to data requests; the data processor is arranged for configuring fields of a database base core and fields of a database extension core, writing data of corresponding fields into the database base core and the database extension core respectively in response to data requests; the data connector is arranged for creating data connection between the database base core and the database extension core in response to data requests. The integrity and safety of data are guaranteed.
摘要:
A database storage system based on optical disk includes a database management system installed on a server, a magnetic disk storage device and an optical disk storage device connecting, via a data connection, to the server. The database management system processes database management and data management in response to data requests and a database is created in the magnetic disk storage device, and includes a field structure generation module, a record index generation module, a storage space allocation module, a storage space status module, a record linkage module, a record split module and a database creation on optical disk module. The integrity of data is maintained during a database backup process. The optical disk containing a subdatabase accepts the management of the database management system to serve as a normal data source. The databases are hierarchically stored using the storage devices. The methods for database backup and restoration are provided.
