MicrosoftHave you seen the updates to SharePoint Framework?

If you expose your SQL throught a REST service, you could then work with your SQL Data. If that it's not possible, you have to rely on Provider-Hosted Add-ins.
I can imagine the authentication side of that getting complicated but I'll see what I can find. Now I've seen the new framework I don't want to go back to using iframes!
