Book(s)?

[XL-Dennis Consulting]

I read somewhere at REALbasic's forum that 80 % of Valentina DB are common db knowledge
that we can apply. I can accept it when it comes to DBs administrators/developers.
However, we who don't have that background may need some help here and books is a good
source. But the only book I have found is from a publisher by name of Betascript
publishing and the title is "Valentina Databases". Does it exist any other book? If
not, what about this book?

TIA,
Dennis
