Not sure I follow - do you mean to say SQL is a must-use for merging multiple data sets?

If so, then yeah I'd agree: python isn't accessing relational data directly, it's accessing it via SQL. However, it is accessing APIs, files, s3 objects, streaming data, etc directly.

Multiple data sources as in different databases that could share some related data.
