Data Refresh Data Flow

Data refresh occurs when enterprise information system (EIS) data updates are propagated to the Unwired Server cache database (CDB).

There are two general categories by which data refresh occurs:

Unwired Server pulls – pulls updates from the EIS either through Unwired Server configuration or policies defined by the MBO developer.
EIS pushes – a DCN option that includes all information required for an update are pushed to Unwired Server.

Data Change Notification Data Flow
Data change notifications (DCNs) refresh data when a change to the enterprise information system (EIS) occurs.
Cache Group Data Flow
A cache group policy determines the frequency and the level to which mobile business objects (MBOs) belonging to that group are refreshed.
Cache Update Policy Data Flow
A cache update policy provides a variety of options by which data refresh is controlled for a given create, update, or delete operation, ranging from applying only the results to the cache to invalidating the MBO and refreshing all data (invalidate the cache).
Data Refresh Initiated by Unwired Server
Configure Unwired Server to "poll" the enterprise information system (EIS) at scheduled intervals to determine if data has changed. If it has, the EIS refreshes cached MBO data.
