This enables
data integration that is independent of the schema definitions and attribute information of the
source data. [Solution] A
data integration support system that assists in the process of integrating data from a group of
source data files into a destination
database comprises: a schema information generation device that generates
source schema information defining a source
database which is a
database of the group of data files; a suggestion device that presents the user with suggestion information showing possible table options in the source database for each table in the destination database, based on the relationships between tables in the
source schema information where tables refer to other tables and the relationships between tables in the destination schema information which defines the destination database, and prompts the user to select one of the options; and a
data integration device that determines which tables in the source database will be integrated into each table in the destination database based on the user's selection of options.
