One Model supports both destructive and incremental data uploads. A destructive data upload removes any previous data from a given source and replaces it all with the new data in your file. An incremental file upload keeps the existing data in place but appends any unique new data in your file upload. The video below will take you through how that works. 

Incremental file uploads may also be referred to "delta" files in some contexts. Delta because it's just the changed data since the last import. 

Note: Destructive and incremental data refreshes work on APIs as well as file uploads. In the case of API imports, One Model's API connectors handle the logic necessary to append or replace data.
