Agreed, I would also like to suggest to use database views whenever
possible. Creating read only views (these are generally read only
already) for each tabular data which has to be displayed on a web site
is generally a good practice - depending on the environment you are
on, it is also generally faster because it accomodates better when
used in combination with EJBs or other sort of
caching/Model-View-Controller mechanisms.
Cheers
