Offline/online Synchronisation

Hi All,

I am attempting to write a new GWT application. One of the requirements for this is being able to use the app when not connected to the web. When the connection is restored, any changes are applied to the server from the client. This therefore means that there will need to be a copy of the server data maintained on the client. In addition, the application should sync back to the server every X minutes when in use.

From what I have read, I think it should be possible to do this using the following:

> PHP on the server to interface with a MySQL database
> RestyGWT to make the calls to the server PHP and handle passing/receiving of JSON

So first question is, is my understanding correct? If not, how would I be able to accomplish what I want to do?

However, if my understanding is correct, would someone be kind enough to a brief explanation/outline of how this would be accomplished as I am a bit of a GWT newbie and the stuff that I have found by my own searches has left me somewhat confused!

Many Thanks

Tim
