Data Tier

The data tier stores data used by SAP Mobile Server and the management console within the runtime landscape.

Four categories of data are persisted and managed in the data tier:

Cache data is stored only for applications that use synchronization and maintains records of device synchronization activity along with any cached data that may have been retrieved from the back end or pushed from the device.
The application package hosted in SAP Mobile Server communicates to the CDB through JDBC connection pools that are configured from the administration console. The MBO parameters and the relationships between MBOs define the shape of the cache tables. The internal implementation of these tables and the associated queries are not public and may change from release to release.
Cluster data maintains knowledge of and coordination between SAP Mobile Server clusters.
Monitoring and domain log data stores monitoring, tracking, and log messages for application activities.
For applications that employ messaging services, HTML5/JS Hybrid Apps, OData SDK and applications that use notification mechanisms, this data stores in-transit asynchronous messages until they are processed by the mobile application infrastructure layers. Message data is encrypted on the device and in transit.
