I didn't claim RDBMSs are interchangeable or that there are no differences. I disputed the statement that "databases are only trivially interchangeable for trivial cases." That has not been my experience: changing out one RDBMS for another is not trivial, but it's easier and more controllable and predictable than changing out application code. I also disputed the notion that reading a book first would enable someone to choose the right tool the first time. There's no substitute for experience and real expertise, and you only get that by trying things and making mistakes, or at least learning from other people's mistakes.

. . ."databases are only trivially interchangeable for trivial cases." That has not been my experience: changing out one RDBMS for another is not trivial, but it's easier and more controllable and predictable than changing out application code. Keeping the punctuation but replacing the words with symbols: "X." Not X: X, but tangential comparison. Sounds like you actually agree with me, but don't see that as a reason not to make much hay about disagreeing with me. :)
