Cached Updates are dead - long live cached updates?

Greetings from South Africa!

I recently completed an app using cached updates. I know that these
are no longer the "preferred" method and that TClientDataSet should
be used.

Does anyone know then if Delphi 4 - professional drops cached updates?
Does it include TClientDataSet (which I thought only came with the C/S
version) ? Can anyone give me some more information as I am about to
upgrade from ver 3 to ver 4

Thanks in advance

Delphi 4 continues the use of cached updates. In fact, various fixes were
made to resolve problems in earlier versions of Delphi. And yes, the
TClientDataSet class is only available in the Enterprise edition (the name
replacing the previous Client/Server edition) and not in the Professional
edition.

As far as which is the "preferred", it depends on what edition of Delphi 4
one has: Enterprise or Professional. In the Enterprise edition, the
TClientDataSet is the preferred approach -- though you can still use cached
updates if desired. In the Professional edition, cached updates are the
*only* approach available, so I guess it is thus technically the
"preferred" approach.

So if you have been using cached updates in applications created with
previous versions of Delphi, they will still be supported (in fact,
improved internally) through Delphi 4. This is true even should you upgrade
to the Enterprise edition.
