A synchronization system may include: A Source (outbound). An "Accessor" communicating with a device's data store. A corresponding Target Accessor is provided for inbound data. Both Accessors work in conjunction with a "Conduit," which is provided for understanding the data that is being read so that the data can be mapped to a universal schema or "unirecord" or to a target dataset. The Conduit serves to broker the services of the Source Accessor and the Target Accessor and to provide field mapping and conversion. Core synchronization functionality is provided by a Synchronizer or "Sync Core" (engine). The Synchronizer performs its specific functionality on a per record or per data item basis, such as determining which records need to be inserted, deleted, updated, or the like.
