PERTURBATION OF A SHARED, DISTRIBUTED CUBE

摘要

A method of performing a query on a cube of data is provided. A cube of data is distributed onto a plurality of computing devices with each computing device of the plurality of computing devices storing a different portion of the cube of data. A perturbation rule configured for application to the cube of data and associated with a user is received. A process space associated with the user is created. The received perturbation rule is compiled in association with the created process space. A query on the portion of the cube of data stored at the computing device is received. The received query is associated with the created process space. The query is processed while applying the compiled perturbation rule to data extracted from the portion of the cube of data stored at the computing device. A result of the processed query is sent to a requesting computing device.

主权项

1. A computer-readable medium having stored thereon computer-readable instructions that when executed by a computing device cause the computing device to:
receive a perturbation rule associated with a user, wherein the perturbation rule is configured for application to a cube of data, wherein the cube of data is distributed onto a plurality of computing devices with each computing device of the plurality of computing devices storing a different portion of the cube of data, wherein the computing device is one of the plurality of computing devices; create a process space associated with the user; compile the received perturbation rule in association with the created process space; receive a query on the portion of the cube of data stored at the computing device, wherein the query is associated with the user; associate the received query with the created process space; process the query while applying the compiled perturbation rule to data extracted from the portion of the cube of data stored at the computing device; and send a result of the processed query to a requesting computing device.
