Optimization of database network traffic based upon data-use analysis
First Claim
1. A method of processing a database query from a client in a client-server database management system, the method comprising:
- receiving a database query from a client;
responding to the database query by returning to the client only a subset of the data requested by the client in the database query based upon a usage statistic associated with the database query such that less than all of the data requested by the client in the database query is returned to the client in response to the database query, wherein the usage statistic is based upon automatically tracked usage data that is indicative of how data requested by the client is used by the client; and
during a current or prior execution of the database query, generating the usage statistic by automatically tracking the usage of data returned in response to the database query during the current or prior execution of the database query to identify data from among the data returned in response to the database query that is unlikely to use, wherein the subset of data excludes data identified during automatic tracking as being unlikely to use.

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.

15. A method of processing a database query from a client in a client-server database management system, the method comprising:
-
receiving a database query from a client, wherein the database query requests a plurality of rows and a plurality of columns from a table stored in the database management system; generating a usage statistic associated with the database query and indicative of how the data requested by the client is used by the client during a current or prior execution of the database query, wherein the usage statistic is based on automatically tracked usage data and identifies data from among the data requested by the client that is unlikely to use; determining a subset of data to return to the client in response to the database query based upon the usage statistic, including determining at least one of a subset of the plurality of rows and a subset of the plurality of columns anticipated to be used by the client, wherein the subset of data excludes data identified during generation of the usage statistic as being unlikely to use; and responding to the database query by returning to the client only the subset of the data requested by the client in the database query such that less than all of the data requested by the client in the database query is returned to the client in response to the database query. - View Dependent Claims (16, 17, 18)

19. An apparatus, comprising:
-
at least one processor; and program code configured to be executed by the at least one processor to respond to a database query from a client in a client-server database management system by returning to the client only a subset of the data requested by the client in the database query based upon a usage statistic associated with the database query such that less than all of the data requested by the client in the database query is returned to the client in response to the database query, wherein the usage statistic is based upon automatically tracked usage data that is indicative of how data requested by the client is used by the client, and wherein the program code is further configured to, during a current or prior execution of the database query, generate the usage statistic by automatically tracking the usage of data returned in response to the database query during the current or prior execution of the database query to identify data from among the data returned in response to the database query that is unlikely to be used, wherein the subset of data excludes data identified during automatic tracking as being unlikely to use. - View Dependent Claims (20, 21, 22, 23, 24)

25. A program product, comprising:
-
a recordable computer readable medium; and program code stored on the recordable computer readable medium and configured upon execution to respond to a database query from a client in a client- server database management system by returning to the client only a subset of the data requested by the client in the database query based upon a usage statistic associated with the database query such that less than all of the data requested by the client in the database query is returned to the client in response to the database query, wherein the usage statistic is based upon automatically tracked usage data that is indicative of how data requested by the client is used by the client and wherein the program code is further configured to, during a current or prior execution of the database query, generate the usage statistic by automatically tracking the usage of data returned in response to the database query during the current or prior execution of the database query to identify data from among the data returned in response to the database query that is unlikely to use, wherein the subset of data excludes data identified during automatic tracking as being unlikely to use.
