Design Issue

Hi once again,

I have been asked to add a feature that allows a person to add content to a
site via a control panel. This control panel is basically a form that will
have certain fields such as subject, body, date. The site is supposed to
show the content that is supplied to it via the form that is part of the
control panel. I was thinking that there's a good chance that the data that
leaves the form and that is then stored in a database may not change
frequently. Because, this might be the case, would it be more efficient to
come up with a solution that would only go to the database if and only if
something has changed. I was thinking that as soon as information has been
queried from the database to appear as information on the website it should
also be turned into a static page. If it is a static page and no further
activity (addition or modification of existing control panel information)
has occurred then it would be more efficient to grab the static html page
rather than query the database and possibly retrieve information that has
not been modified.

Is this solution a viable one and if so how could it be implemented?

I think there is a file system object something-or-the-other that perhaps
could be used to create the html file on the server. Maybe I could keep
track of the last modification date of this file or creation date and
compare it to the last date of the data that was inserted in the database.

Any suggestions

Thanks in advance

Terry
