Method of handling data retrieval requests

摘要

A method of handling data retrieval requests is provided. A data server (108) receives a message, which message at least identifies a particular data set (202). The data server (108) determines whether the particular data set represents a complete data set, i.e., a complete and current version of the data (204). When the particular data set does represent a complete data set, the data server (108) confirms that the particular data set represents a complete data set (208). When the particular data set does not represent a complete data set, the data server (108) sends at least some additional data to facilitate the formation of a complete data set (206).
