What changes are you trying to make? (e.g. Adding or removing code, refactoring existing code, adding reports)

I would like to teach views before importing into the db.
Seems trivial, but I have built a new demo around it.

1. Teach view by using a "daily sales" query we have used in previous session. View now exists.
2. Import a new set of values for the customer_purchases table (04_data/external/new_customer_purchases.csv). This has "today's" date as market_date column.
3. We update the view to show dynamically "today's sales".
4. Update market_data_info table with INSERT statement to include today's date info (INSERT is section before Views). View now reflects the data we just imported.

This demo makes use of several concepts across the modules. Has a "putting it all together" feel.

How were these changes tested?

I've confirmed that the new "views--->importing csv" works, both in terms of slides, but also in terms of live demo
