Hi Maxim and APEXers the list, I got APEX 3.2 up and running using the Embedded pl/sql Gateway with 10.2.0.4 running on VMware guest Suse 10.1 and MS Windows Server 2003,... thanks to your help I've now read (most of) the 2 day development guide that comes with the build and have produced a simple prototype. I have a few changes that I need to make after a demo, but both client and I are happy. Nice one :-) Very impressive. But,... My app was *very* simple, and therefore straightforward. But with such a powerful tool I can envisage creating a bird's nest of an application that works a treat and is *totally* understandable and maintainable at development time, but a few weeks/months down the road is a bit of a mystery. I wonder how complicated a "simple" app would have to be before maintenance became a nightmare. How are these APEX applications designed from scratch, especially when the app is expected not to be trivial. And once designed, how is that design documented? Regards Tony
