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.
