The underscore character is the almost universal word separator in
programming languages, and it's hard to imagine a database that wouldn't
support its use in column and table naming.  There did use to be a small
problem in R:Base, if you named a My_Table and tried to do LIST My_Table
R:Base would give you an error.  You had to do LIST TABLE My_Table.  This is
no longer true.

I generally prefer the upper/lower case method with no underscores.
Fortunately, R:Base preserves the casing of table and column names, some
other database convert them all to lowercase or all to uppercase, making
them much harder to read in listings.
