Separation Model With Sync

I've got a project that requires this easy sync capability. Also, the database being discussed also benefits from the Separation Model(UI/Script File and a Data Only File) I'm just looking for general pointers on this setup with regards to getting the data onto the server and how this generally works with a separation model..(external data sources, etc)

One particular thing is that I'd like to be able to do is development and interaction with the UI file on the live server and then be able to distribute the updated UI file to the syncing clients when it's ready. As a developer, I don't need the sync capability and to carry the data locally, but I do need to editing ability via remote server. 

Thanks.
