Abstract
In a computer system, an SQL as a content of data processing request by a database independent protocol (protocol connected to a DBMS) that is issued by an applicationis converted from an SQL for an old DB before a migration to an SQL for a new DBMS, then converted into a protocol that depends on a new DBMS, and then provided to the new DBMS. This operation is realized by an extension DB connection middlewarethat is obtained by extending a DB connection middleware that does not depend on the DBMS or an application.
