How does this pic show that Elon Musk doesnt know SQL?
I'm a tech interested guy. I've touched SQL once or twice, but wasn't able to really make sense of it. That combined with not having a practical use leaves SQL as largely a black box in my mind (though I am somewhat familiar with technical concepts in databasing).
With that, I keep seeing [pic related] as proof that Elon Musk doesn't understand SQL.
Can someone give me a technical explanation for how one would come to that conclusion? I'd love if you could pass technical documentation for that.
You're viewing a single thread.
I think a lot of comments here miss the mark, it's not really just about stating the gov does not use SQL or speculation regarding keys.
Deduplication is generally part of a compression strategy and has nothing to do with SQL. If we're being generous he may have been talking about normalization, but no one I have ever met has confused the two terms (they are distinctly different from an engineering perspective).
There are degrees of normalization too, so it may make total sense to normalize 3NF (third normal form) rather than say 6NF depending on the data.
Thats interesting. I didn't know anything about normal forms, but a quick glance at G4G has some interesting information. I don't have the time to go through their full article at the moment, but its been added to my to do list.

This is it, relational databases are normalized under forms, deduplicate is usually a term used when talking about a concrete data set from data sources like a database, not the relational data model in the database itself.
