The organization wanted to have a shopping cart for their members-only merchandise, but they did not have database support at their web host,so the solution I pursued was to develop their shopping cart entirely in OBJECT-ORIENTED Javascript.
The javascript works in a data-island, and contains objects for the customer's shopping basket, the store's merchandise offerings and a few others. All of the processing is done on the client side asynchronously, which makes it very fast.
This programming approach has come to be called AJAX in the last year, of course at the time I did it, it had no such name.
