Indeed, what's particularly interesting in the data is just how much open source databases have already become the de facto enterprise databases.
Your next enterprise database is almost certainly going to be open source. No, I'm not saying proprietary databases like Oracle are dead. Nor am I suggesting that developers who have a command of SQL Server don't get paid (and quite well). What I am suggesting is that there's clearly a perfect storm brewing for open source databases, as revealed in Stack Overflow's 2020 survey of over 65,000 developers.
