----------------------------------

Reposting from Pull Request...

Robin,

I recommended in the thread that it would be more ideal to have the DAO be 
"Persistence Mechanism" Specific rather than database vendor specific. For 
instance, note that your code replicates identical classes for Oracle and 
Postgres, only being different in the "name" of the dao.

It would be better to have a "LegacyDAO" for the current implementation, then 
be able to look at technologies like JPA and JDO for alternate DAO 
possibilities. Likewise, this would Liberate us from having to implement every 
single rdbms vendor as separate DAO in the future.
