Methods, systems, and computer program products for cache conflict detection are provided. A computer-implemented method may include providing a partial graph of data to an application executing on a mobile device where the partial graph is derived from a document comprising a graph of data having a plurality of nodes, receiving a modified partial graph from the application where the modified partial graph includes one or more changes to the partial graph, and determining a document version used to derive the partial graph is no longer a most recent version of the document.

Cache conflict detection

Methods, systems, and computer program products for synchronizing data between a mobile application and an enterprise data source are provided. A computer-implemented method may include receiving a request for data from an application executing on a mobile device, receiving a document including the requested data from a data source where the document represents a graph of data having a plurality of nodes, and providing a partial graph of data to the application where the partial graph is derived from the received document and at least includes the requested data.

Composite graph cache management

Systems, methods, computer program product embodiments and combinations and sub-combinations thereof for data caching and cache synchronization are described herein. An embodiment includes comparing data in a cache with data stored at a data source and determining database operations needed to synchronize one or more partitions of the cache with the data source. Each cache partition is associated with mobile business object (MBO) metadata of a distinct mobile device and the determined database operations are executed to synchronize the partitions with the data source. By refreshing only those partitions which are pertinent to a given device, embodiments of the invention may increase parallelism by allowing multiple partitions to refresh concurrently. The embodiment further comprises reviewing a caching policy associated with the cache. The caching policy may be selected in a manner that reduces data traffic and redundant requests on the data source.
