Abstract
Local data caching for views with linked attributes are optimized based on net change notifications. Data requests may be made periodically to a server, each request with a specific set of constraints on timestamps of entity types involved in a view and each ordered by a primary item's identifier (ID). Applying the results of these requests to a client-side cache of the view results enables the client-side cache to stay 'relatively fresh' with respect to the server's data. The server may handle view data requests where all conditions on related tables' columns are applied with an 'and' operation, and the specific set of conditions on the timestamps of the related items are applied to get the net changes with minimum redundancy. The server may also handle stateless view data requests limited by the number of results, and a “sort by ID” may be applied to ensure consistent results over time.
