Thank you for the article, very accurate and above all easy to understand. I think the real step forward happens when we stop considering SQL and Python as separate tools and start thinking about where it makes sense to process the data and where instead it makes sense to move it.

For example, filtering and aggregating correctly on the database side before bringing everything into Python can make the analysis much more efficient, especially as datasets start to grow.

So, to really take advantage of the synergy between these tools, I believe we need to understand how to build a sensible and sustainable data flow, in addition to knowing the correct syntax (which is obviously absolutely fundamental).
