[dba-VB] Browser based database

Hello John,

There are lots of things to consider when you out an app online, security
being just one.  But there are really many other things also, most of which
I do not know.

However, I am currently happily developing web apps myself, and I spent
minutes and hours on my coding.

I am using DotNetNuke as my framework and it works a treat.  I keep it
simple and try not to get too fancy.  There is loads of help available from
the groups and forums.

It is not too wild to suggest that in the future 50% or more of our
customers will want web based front ends, so I urge you to study DNN - a few
days of reading the forums and the turorials on module development will have
you coding apps in no time.

Do not be put off by the initial barrier to entry, once you get the hang of
it, and one you keep it simple, you can code in the same ol' c# style , but
your GUI will be a DNN website.

Oh, and it if fun also.

Mark
