Abstract
A database client which can access a plurality of databases copies data selected from a source database to a destination database. The database client compares attribute items of attribute information appended to the data to be copied with those which can be set in the destination database, and directly copies an attribute item which can be set in the destination database to the corresponding attribute item. On the other hand, the database client copies attribute information of an attribute item which cannot be set in the destination database to a predetermined attribute item in the destination database. In this way, upon copying data between databases with different kinds of attribute information that can be set, the destination database can hold the attribute information of the source data.
