ABSTRACT:
A derived database processing system in a database processing device comprises a plurality of independent databases which can provide a plurality of users with a group of data to be shared for a common purpose. The derived database processing system comprises a dictionary for managing database logical definition information and database storage information in a secondary memory, a derived database registering unit for determining a definition frame of a new name without violating a definition frame of a name used in a schema definition which defines data in a database, a dictionary information manipulating means for referring to said dictionary when the manipulation target is a derived database, then selecting necessary components of said database, and a database processing procedure generating unit, in a binding process to optimize access routing in a database.
