Is There a Cross Data Base Joint?

There's some big data sharing vendors on there, like the one that comes to mine. They're really well known in the financial services space. The two most popular ones that i understand are out there is actually weather and covid 19. But what you've alluded to is still a challenge. Like your internal data set may have different join keys or structures than that weather data set. There still is a whole process around making it publics but at the same time, there still as that data engineer, at least business analysts, data professional that has to match that data.
