Hello, we need to read externals system data using Web Service/REST in SharePoint 2013 online and we have Office 365 E3 version.
I would like to have and expert opinion on the same if we have web services which is exposing data to us and which we can call directly from Client side in an app, Is any need of BCS arise in this case really? What is really use of BCS if web services there to expose data which can be consumed by SharePoint?
Any information/experience/challenges about this would be highly appreciated. Thanks
