ABSTRACT:
An apparatus, program product and method utilize one or more usage statistics, which are reflective of what data is actually and/or likely to be used by a client when processing a database query, to reduce or eliminate the transfer of unnecessary data between a client and server in a client-server database management system. Information such as the columns that are or have been used and/or the number of rows that have been accessed, may be utilized to identify certain data that is likely to not be used during processing of the database query. Based upon the data that has been identified, a subset of the data that would otherwise be returned as a result of the database query may be identified and returned to a client, often substantially reducing the amount of data required to be retrieved by a client in connection with a database query.
