SogiRoom

A tiny web app in the browser which allows one to book a room. Toy app made to explore 'rich' Internet applications, concurrent modifications and optimistic replication of data between a server and multiple Javascript clients.

Challenge

How a RIA, hosted in the client browser, can make use of a local data store to avoid server communication, and how the data store syncs with the server to commit changes and resolve conflicts using optimistic replication techniques. See survey by Saito/Shapiro (2005).
