Abstract
A sync server responds to messages from a client to synchronize data between a client dataset and a reference dataset. Various messages may be received from the client, including changes to the client dataset, requests for confirmation of received changes, or requests for changes to the reference dataset. When the server receives client changes, the server reads record ID's from the messages, writes the ID's into a change ID list, and places the changes into a queue for processing. When the server receives a request for confirmation of changes, the server uses the change ID list to confirm receipt of changes, including changes that have not yet been processed. If the server receives a message that requires that the reference dataset be up-to-date, such as a request for changes from the reference dataset, the sync server processes all of the changes in the queue before processing the new message.
