2. What Is: Occasionally Connected
12/24/2017 3:50 PM
What Is: Occasionally Connected
Empowering users to leverage their computer, applications, data and files regardless of network availability
Application proactively retrieves necessary data necessary to work offline
As the network comes available, the application will automatically sync their work and log conflicts for the user to resolve
Network operations occur in the background so the user can stay focused on their task
Example: Outlook 2003
Burping Netowrk – Product Studio goes down, you should be able to continue working
Working in the field: Take you laptop and work for extended periods of time
