The SYNC Add-in utilizes the Microsoft Sync Framework to provide the ability to link databases, enabling update of data periodically when users have been offline for periods of time.
The Microsoft Sync Framework uses a Hub-Spoke topology, with a single central database as the hub and all other databases acting as spokes.
Any data (including templates) can be transferred between a hub database (i.e. central database) and one or more spoke databases (i.e. remote databases). This allows data to be collected on spoke devices, with any changes sent or received from the hub database with the click of a single button.
Terminology
•Topology – defines the configuration of the computers and servers forming a network
•Hub (aka Remote) – refers to the central database
•Spoke (aka Local) – refers to offline databases on devices that synchronize with the hub database
•Scope – refers to a set of tables and filters defining a synchronization
•Provisioning – refers to the process of defining which tables and filters are used to synchronize data between the hub and spoke databases
