Ideally, you would implement the Sense Server platform. Then the server would take care of reloading the data on schedule and colleagues would access using the Access Point.
If you use the Qlik Cloud, you will need to run the reload locally and then update the cloud copy.
If you use Qlik Desktop, you need to distribute a separate copy to each user for install on their local machine. If they want to refresh their copy, they will need the proper database driver and access. Alternatively, you can reload on one machine and redistribute the updated copy. However, if the user made any self-service updates to their own copy those updates would be lost.
