Abstract
Embodiments relate to systems and methods for online query processing, in which a SQL or other query server can generate a record of results served to clients. The distribution record of results, referred to as a distribution map, can record the identity of properties of database entries or other content that has been distributed to individual clients. When a client transmits a query whose results include properties that have already been served to that client, the re-transmission of that information can be suppressed leading to improved communications efficiency. A notification function can be provided whereby all users receive updates to the properties or content they have already received, when those data components have been updated in the underlying database. The delivered content can relate to personal contact lists, media play lists, or other information displayed in an application or Web service.
