Visual Builder allows you to create applications that can continue to function even when your device is disconnected from the network. To do that Visual Builder leverages the Oracle JET offline persistence toolkit. This toolkit enables your application to cache data on the client and serves it back from the cache when you are issuing the same REST call but your device doesn't have access to the server. It also allows you to "execute" operations such as adding records while offline - storing those requests on the client again - and then automate replaying them back when you are connected.
