Someone linked me to the article Against SQL recently and it resonates with me a lot. I have a temptation to write a new SQL-like relational query language that tries to fix as many of these problems as I can, but this seems unreasonably ambitious for someone whose background is not databases (and who already has like 3 personal projects ongoing...)

(To be clear, I think unreasonable ambition is sometimes commendable. But I want projects that I'll actually finish.)
