Architecture of Morrisons OrderPad

Morrisons OrderPad is a tablet web-application that helps staff in supermarkets place orders for new stock as they walk around the store. My colleague Rob Miles and I felt that the resulting application makes a good expositional architecture for a tablet web application backed by a lightweight java server. We highlight the separation of application control and DOM interaction on the client, using small, focused frameworks on the server, the broad-stack testing environment, and the use of a pilot project to understand what features were needed.
