Hi Sumedha, First of all thank you for your prompt reply, it took me long to find someone to answer :)
Let me ask further. Right, we can assume stratos live. Then let's say I deploy saas enabled carbon application. After it, I understand stratos live tenants login to my application but I'd like them to access their data source within my application. Does it make sense? Is it possible? Thank you.
