UPDATING A LARGE DATASET IN AN ENTERPRISE COMPUTER SYSTEM

A method of updating fields of records in a dataset mediated by a database management tool (DMT) that does not an API function for updating individual fields of records. The method comprises adding a temporary field to each record in a dataset by the DMT, copying a subset of the records in the dataset by an application that is not the DMT, changing at least one field in each of the copied subset of records by the application, changing the temporary field of the copied subset of records by the application. The method further comprises adding the subset of records to the dataset by the DMT, aggregating, by the DMT, the dataset based on a selection criterion defined with reference to the temporary field, wherein aggregating removes conflicts between records that have the same unique identifier based on the temporary field values of the conflicting records.
