@cvogt can you please send me some citation or documentation of this concept?

As I said, large swaths of the SaaS industry follow the rails conventions, which are lower case:

As you can see in the MySQL documentation, they make no mention of quoting influencing table and column identifier case sensitivity; in that database, it's depends on the filesystem case sensitivity:

Googling didn't show me much, but I found this on StackOverflow:
http://stackoverflow.com/questions/153944/is-sql-syntax-case-sensitive

Can you please provide a source for this assertion?
