To me, CJ Date is the one who makes it crystal clear. Not in his main book,
but in his Relational Database Readings books, which I have most of.
I have also seen some good articles by Fabian Pascal.
I also have a new book called Data Modeling for Everyone by Sharon Allen,
published by Curlingstone Press. It deals with how to actually do it - take
it from conceptual to logical to physical, going straight to a physical
model - which we all sometimes have to do, and how data modeling fits into a
software project. Very good book.
Otherwise, throw a problem out here and see if anyone here has ideas that
may help you. I've loved data modeling my whole career and believe I could
write a book myself about it (I didn't say anyone would read it!).
I'm afraid that by turning it into DBA speak you might mean not
understanding the essentials of data modeling. That wouldn't be good. I
would take the most important things to remember and have an example in the
real Oracle world of what that means.
I personally believe that the most important thing to remember, the
essence of a lot of data modeling, is that there should always be only one
place for an item of data to go. Denormalization typically creates another
place for it to go, so you have to remember to update two or three or four
tables with the same data.

english?
I swapped emails with a member of the list and Im having trouble seeing how
you can take 3NF, BCNF, etc... and turn that into DBA speak. One of the guys
told me that BCNF essentially means you have a key that you can put a unique
constraint on. Well that makes this much easier to understand.
All my theory books just discuss theory. Anyone know some that split the
difference. IE, not Codd, not CJ Date, Not the academic textbooks.
Thanks.
