ok...what I'm trying to understand is if jsreport can be used to create dashboards and report for an application backed by a database..
It would be a good use case for jsreport or I'm completely on a wrong path?

Oh, thank you.
Is this the only way? Is there a way of importing for example a csv file? or even post data through API?

Just playing around, my data are in different databases, mysql, postgres, RDS, how do I connect, extract or migrate them to use them i jsreport?
