Comparison of relational database management systems: I found this Wikipedia page at the bottom of the SQL comparison I linked to yesterday. It’s a comparison of major database platforms and their support of various features. It doesn’t get into the SQL like the other page, but there are more platforms to look at and more high-level features covered.
I’m surprised by how bare-bones MySQL is. I knew it was stripped down, but it looks worse when you see it laid out like this.
