Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method of an appropriate preprocessing for a migration between database systems. SOLUTION: An operating state of a first database system is analyzed to generate a table for conversion (S101). The table for conversion converts a first database connection-control character string having a connection character string including a first SQL sentence for a first database engine of the first database system and a database control character string, into a second database connection-control character string having a connection character string including a second SQL for a second database engine of the second database system and the database control character string. After the table for conversion is generated, it is used for migration of the first database system to the second database system. COPYRIGHT: (C)2010,JPO&INPIT
