Comparing two data sources in a data table or visualization?

Hello,

I was wondering about how I can compare two different data sources but have the same field. For example, I want to do analysis by comparing users that are present in one data source and user that are disabled from another data source.

Users from both sources will be under "user.name"

Is there a way to display this as a visualization? a data table?
Is this possible?

Thanks,
Erik
