I work in an Oracle shop. My I.T. department uses ArcGIS Online to host data for use in data collection activities.
The data goes through a yearly cycle:
- Export from our Oracle enterprise geodatabase
- Import to ArcGIS Online
- Edit on tablets or phones via the Collector app during the course of the year
- Export to a file geodatabase
- Process the data
- Import back into the Oracle enterprise geodatabase
I'm involved in steps 1, 5, and 6. But, it has occurred to me that I have no idea what goes on in step 2. Out of curiosity, what is the underlying DBMS of ArcGIS Online?
