OK, you can handle network changes and make it easier for the users. But what if
the connection drops? We have been to places where even the phone network is not
available??”the signal strength indicator showing zero bars instead of the full five.
What can we do in such a situation?
Nothing. We can't do much in such a situation. All we can do is keep a large enough
session timeout to handle small interruptions, but we can't handle total disconnects.
Or can we? What about the entire buzz around "Occasionally Connected Computing"?
Occasionally Connected Computing
Occasionally Connected Computing (OCC) is a term coined by Adobe while
referring to some of the Rich Internet Applications (RIA). These applications could
cache data to the client and function even when the Internet connection was not
present. We use the term in the same manner for mobile applications. OCC refers to
the kind of software architecture where an application can continue functioning with
or without a live Internet connection.
OCC requires a different way of thinking about software architecture. But the ability
to run an application without a live connection has tremendous impact on the future
of the mobile web.
