Simplist way is to add methods in the constructor and destructor
to 'Retrieve Self' and 'Store Self' from relational DB - the problem is then
where does the object reside?
It really has to be shared (so that you don't instantiate multiple
instances)
This is the basis of a 3 tier solution but I'm now getting out of my depth
so I shut up
A quick note re thin Clients - A Browser! are you joking. If it supports
HTML, ActiveX, Java, XHTML, XML and multiple Add-ins
then is ceased being thin past HTML - back to my point - if something is
delivered with the OS is it immediately thin then
M$ is some sort of Technological Jenny Craig
and Dennis re performance of CPU are you stating that by definition a Sun
Workstation front end to a Cray 2 cannot be a thin client - its all relative
and we should not simply look at things in terms of PC's - They are still
toys
