Abstract
A data conversion job used for data conversion is separated into a data conversion server job for executing conversion processing on a data conversion server and a storage job for instructing a copy of a table on a storage device. Then, the storage job is executed to instruct the storage device to copy the table. The data conversion server job is executed only for fields that need to be converted, and thereby data conversion is performed for the copied table. This makes it possible to reduce a load of the data conversion server when converting data of a database, and also to enable a designer of a data conversion job to easily design the data conversion job.
