HERE As for storing the data, again how are you receiving the data? Are you physically receiving the data key? Are you receiving a backup file made from the data key?
If you are physically receiving the key, then all you need is a key downloader plugged into your computer and the Key Downloader service enabled in Checkmate, then simply insert the key into the key downloader and the data will be downloaded into the live database.
If you are receiving the backup file made from the data key, then you will need a key downloader as above and a key and you can restore a backup key(Vehicles & Devices->Troubleshooting->Restore Backup Key) and after restoring you can remove and re-insert the key and the data will download into your live database.
If its neither then in what format is the data?
