Enhancing Data Cubes

摘要

A data server receives multiple requests for data cubes that include data related to a user-specified subject matter. The requests are aggregated into an aggregated request, and an initial data cube is retrieved based on the aggregated request. Upon determining that the initial data cube fails to provide requisite data needed by the aggregated request due to data being missing from the initial data cube, the missing data is located and identified as augmentation data. The initial data cube and the augmentation data are sent to senders of the multiple requests for data cubes. In response to a new request, from a new requester, for a data cube that provides data related to the user-specified subject matter, the data server presents the new requester with an option to purchase the initial data cube at a first price and the augmentation data at a second price.

主权项

1. A data server comprising:
a request receiver for receiving multiple requests for data cubes that include data related to a user-specified subject matter; a request aggregator for aggregating the multiple requests into an aggregated request; a data cube retrieving logic for retrieving an initial data cube that is related to the aggregated request and the user-specified subject matter; a determination logic for determining that the initial data cube fails to provide data related to the user-specified subject matter beyond a predetermined value due to one or more sets of data being missing from the initial data cube; a first price setting logic for establishing a first price of the initial data cube based on said determining that the initial data cube fails to provide data related to the user-specified subject matter beyond the predetermined value due to one or more sets of data being missing from the initial data cube; a locating logic for locating the one or more sets of data that are absent from the initial data cube; a second price setting logic for establishing a second price for each of the one or more sets of data according to a level that each of the one or more sets of data causes the initial data cube to approach the predetermined value; a data cube provider for providing the initial data cube and the one or more sets of data to senders of the multiple requests for data cubes; a new request receiver for receiving, from a new requester, a new request for a data cube that provides data related to the user-specified subject matter; and an option provider logic for providing the new requester an option to purchase the initial data cube at the first price and the one or more of the sets of data at the second price.
