Abstract

An optical disc based external data storage system for a database comprises a server, and a magnetic disk storage device and an optical disk storage device both connected with the server in a data mode. A database management system, an external storage management system, an application program interface and an extension server are arranged on the server. A magnetic disk database and a database external storage zone are arranged on the magnetic disk storage device. Parts of field data recorded in the database are correspondingly stored in the database external storage zone. The database management system responds to data requests, and database management and data management in the storage device are completed. The external storage management system responds to data requests, and database external storage zone management and data management in the storage device are completed. The application program interface is used for obtaining information of database external storage data, and database external storage of the storage device is completed. The extension server is used for establishing the database external storage zone and determining the positions of the database external storage data in the external storage zone. Database performance and data reliability can be well improved.

Description

Technical field [0001] The invention relates to a data storage system and a data storage method, in particular to a data external storage system and a data storage method of a database. Background technique [0002] With the development of the Internet and information technology, data has grown exponentially. More and more data and electronic documents in various formats can be seen everywhere, and the information society has entered the era of big data. [0003] To make full use of big data, the first is to store the big data for a long time, and the second is to find the required information from the big data in an effective and fast way. Saving, searching and using big data involves data structures, data formats, databases, and storage media. Data includes structured data, semi-structured data and unstructured data; thousands of data formats; databases include relational databases and unstructured databases; storage media include magnetic (disk, tape), optical (optical disk), ...
