If you design it right, then there should be no changes to the DB at all.
Ie. Just plug on a new front end. To have this kind of ability you will need
a n tier system e.g Something along the lines of Midas, or (EJB etc).
I.e. Your GUI screen is just a view/presentation of the middle tier business
logic.
You could do it all in D5 professional if you use an alternative to Midas

Subject: [DUG]: Lan base vs WAN/Web based Databases
I have a customer based in the US who wants a database which to start with
will be LAN based. 18 months from now he wants to make it a web based app
so that reps can access it from anywhere in the US.
Is there any point in designing the LAN based version and then porting it to
web based or is it a major shift?
The reason I ask this is that in order to set up a web based app we need to
invest lots of money and upgrade to Delphi 6 Enterprise (I currently use
Delphi 5 Professional). This means that the customer will also be investing
a lot more money up front in order to make purchasing Enterprise affordable
for us and the project worth doing.
Also is there any point in looking at other packages that allow an app to be
web based (apart from Delphi Enterprise) that is cheaper?
As an aside - the reason they are asking for a NZ based company is the
exchange rate. i.e. $120 an hour here is a lot better than $120 an hour over
there... Maybe we're not charging enough :)
Thanks in advance,
Steve Aish
