Hello,
I would like to ask for a hint for a good SQL textbook. I don't want just a
reference manual but real textbook with a theoretical background so I could
to design my databases following the general rules as normal forms and so
on.
Try "An Introduction to Database Systems" by C.J. Date - that'll give
you a good background. Anything will do for SQL.
I mean something on the net of course.
I don't know that there is anything on the net that covers background
information well.
