Zusammenfassung:	The invention discloses a heterogeneous type database storage system based on an optical disk, and the system comprises a magnetic disk and an optical disk storage device both in data connection with a server; the server is provided with a relational database management system, a non-relational database management system, a data processor and a database connector; records stored in a database divide fields into two parts through the data processor, one part of the fields is in a relational database, and the other part of the fields is in an non-relational database; fields of the relational database form a child record of the relational database, fields of the non-relational database form the child record of the non-relational database, and the child record of the relational database and the child record of the corresponding non-relational database form an integral record through the database connector. By making use of the advantages and the characteristics of the relational database and the non-relational da
