naming conventions

nouns in all caps will be treated as ordinary words, including abbreviations and is subject to camel caps rules

e.g.
UUID => Uuid
DAO => Dao


Dao should also follow these rules, even in
* ClassNamesDao
* fieldNameDao
* bean id="nameDao"

- the word "name" is to be treated as a suffix, and not as a separate word
-- filename, username, firstname, lastname
