Create related tables and or related features inside of ArcGIS online Instead of using Arcmap and ArcCatalog to create the relates and then uploading or overwriting exisitng services.
Right now I have a relations from signs and mounts to a maintenance log feature, I went with a feature instead of a table so the record would be visable as well as related, but to update the signs and mounts data from our server i have to download the entire feature service group from ArcGIS online, overwrite the data in signs and mounts making sure not to loose the data in the logs and then overwrite the existing service.
So to be clear I do not want to create any relationship outside of ArcGIS online, i would like to be in my map online and create the relationships online. Running the process to download the data and overwrite asset information to protect existing log data takes a lot of time. If this cant be done directly from the map in ArcGIS online it would be nice if i could at least go into the admin of the feature and create the code in the background.
I thought a while back I had run across a post from an ESRI employee that this would be a future ability to create relationships online instead of using the desktop but I can't find it to reference backt to.
