First, I must sadly admit that development on application, that is
system for tracking machines' breakdowns and their maintainance times is
suspended and ceased. That client is very big and their IT had developed
strong addiction to Microsoft/.NET. I suspect they consider running
"something" on their Windows servers which is not windows service and
does not talk to Oracle as unacceptable. Also running dedicated server
is likely against their rules.
Nevertheless I'm pondering about an application for making appointments.
Scenario is simple: you go to website of company or other institution
and will be presented with calendar. You can pre-reserve on some
time/date. You can only see how many outstanding requests are there for
given time. From the company' side someone can pick your request and
make an appointment.
As this is all about time, it needs refresh from browser quite often. To
save traffic/load I am thinking about some periodic scripted
XMLHttpRequest for polling with question if redraw is necessary. Also, I
guess I must ensure that there will be no open forms waiting for input
too long and solve problems such as possibility someone can outrun you
while entering data into a form. Just thinking....
