A system and method of query optimization are disclosed. A complexity measure of a client query received from a client application is compared to a predetermined threshold, which is determined using at least one of system data and query execution data. An optimized query is generated by modifying the client query to reduce the complexity measure of the client query if the complexity measure of the client query exceeds the predetermined threshold. The optimized query is submitted to a server application on a server and a post-processing routine to be applied to the result set is selected.

Method and system for dynamically optimizing client queries to read-mostly servers

A system includes a sensor to determine a user is proximate to the system and a logon module to receive information from the sensor that a user is proximate to the system, receive logon information from the user and identification information associated with the user, authenticate the user to use the system based on the logon information, store the identification information, receive second information from the sensor that the user is not proximate to the system, suspend an operating system session, receive information from the sensor that the user is again proximate to the system, receive second identification information associated with the user, determine that the first and second identification information matches, and resume the OS session in response to determining that the first and second identification information matches.
