From what I've seen of Skywise, it is just a glorified SharePoint. Different systems upload CSV files that get turned into database tables. Then you can define views across these tables that other systems can consume by having them dumped to CSV and dropped on an SFTP.

Performance is not great, so you need middleware and batching anyway. As far as I am concerned, it wouldn't be a great loss if Skywise disappeared and just the SFTP with CSV:s remained.
