Abstract: A system transforms data having a first data structure to data having a different second data structure that is compatible with an executable application. The system includes a conversion template and a conversion processor. The conversion template includes predetermined executable instructions for directing conversion of data source records having a first data format to data target records having a different second data format. The conversion processor maps and converts data elements in data fields of the data source records to data elements in corresponding data fields of the data target records by manipulating data element values and data field characteristics, in response to the conversion template.
