Thank you for responding, I'm adding this follow up about how I made
some progress as it may be helpful to other people.
I've produced two new objects that are very lightweight, Subscriber
with attributes name varchar and Magazine sibling, and Magazine with
attributes title varchar, price float and Subscriber sibling. Then
generated both and downloaded the zip files.
Uploaded the folders to my production server in a passworded directory
then adjusted the configuration files and run setup, in each case the
diagnostics said there was a missing object. So, I copied the magazine
object and put it into the objects folder of the subscriber folder
then re-ran setup. Success - I now have the setup done and can use the
lightweight interface.
Maybe I could have done that a different way, suggestions welcome.
I will now try out what I have with some very lightweight code before
going back to my project.
