Now that I've read the whole article, I'm really not clear what your message is.
In fact, I’d argue that you need to design precisely for specific relational database management systems because, let’s face it, they don’t implement the fundamentals in the same way. If you mess up the fundamentals, you’ve just messed up your entire design.
The point is that you can't take a database that's designed for Oracle, change the t-sql to be Microsoft SQL (or MySQL, etc) compliant and expect it to work well. It'll function. It'll just be slow because the core engines are optimized for different DB design.
