Abstract

Systems, methods, and computer program products are provided for ensuring coherency between user data in a client and their corresponding state in enterprise information systems (EIS) wherein data migrates and subscriptions change over time. A mobile business object (MBO) identifies an update to a subscription or a change in set membership in order to provide updates to a client device and EIS systems. Cached data is filtered for client device users who synchronize data they are interested in (i.e., subscribed to). In an embodiment, the method keeps track of set membership by remembering on a per remote identifier / business object basis the set membership for a parent business object. When set membership changes, the method sends delete notifications to the device to remove ex-members. The method recognizes common relationship types in a business scenario and handles reference-type relationships as well as containment-type relationships. The methods include key tracking and membership tracking.

Description

technical field [0001] The present invention relates generally to user data synchronization, and more particularly to communication methods for tracking and synchronizing changes in user data. Background technique [0002] Remote clients and mobile devices have traditionally relied on synchronizing set member data with an enterprise information system (EIS system) whenever (usually at user-specified timing) connectivity is gained by performing a full synchronization event. For example, when a mobile device is placed in a docking cradle, it has an EIS connection. Once docked, the mobile device performs a full synchronization of uploaded and downloaded collective member data. For the sake of efficiency, the traditional mobile middleware server caches the data from the back-end EIS to avoid repeated access. The intermediary device server also facilitates schematization of the cache for various flavors of references and relationships using some traditional techniques, and allo...
