摘要

The present invention relates to a method for saving, restoring, and implementing a program and data of a database system, in which a command analyzing apparatus receives a save request, and a control unit issues a save request And the restoration order generation means generates the save order of the objects to be saved specified by the control unit with reference to the definition information, and the control unit generates the save, transfer, and restoration order by referring to the definition information, An object to be saved is converted into a SQL command format and stored in a storage medium according to the order generated by the restoration order generation apparatus. The stored data is composed of substitution information, definition information, dependency information, data, a journal and a program. By restoring the system by typing or entering the data bay into another system It is possible to implement the;By taking this, the system can be saved, transferred, and restored by the same apparatus. In addition, since the command format of SQL is used, execution and restoration can be executed without any special means.
