Not everyone needs to cure cancer to do something great.
I mean we're talking about billions of dollars. So much human talent, skill, intelligence taken away from really important things... Just sad...
The only thing is, it needs validation. I hope the company does really well in the long run, and therefore puts 4-day work week on the table for others to follow. Wouldn't that be great...
SQL is easy. Data is hard.
If you aren't investing the work up front to make your data useful then no amount of tooling or magic beans will make writing meaningful SQL easy. If your reports (SQL) are hard to write it's because you have bad data.
Having said that making data exploration easier is always a worthwhile exercise. The more business people can self-serve their questions the better. It falls to data people to make that possible not just with tools but with the data itself.
The advantage of this approach would be the fact that you do the dirty laundry upfront during the modeling & population phases. The end result is a data structure that is fool-proof, i.e. there is only one way to join facts/dimensions, it's self-documenting. In fact pre-joined views could automatically be created (and persisted if need be), giving the business user a clean structure to interact with.
