Abstract: A method can include rendering a first closed curve to a display where the first closed curve represents a number of members of a dataset according to a first criterion; receiving a selection for a second criterion for the dataset; transmitting at least the second criterion via a network interface; responsive to the transmitting, via the network interface, receiving information as to at least the second criterion and the dataset; and rendering to the display, based at least in part on the information, a second closed curve that represents a number of members of the dataset according to the second criterion where the first and second closed curves overlap to an extent that depends on a number of common members thereof.

Abstract: A technique for near real-time reporting of telephone number usage to a computer is disclosed. According to the technique, signaling protocol data is collected for telephone calls that involve telephone numbers associated with the user. The signaling protocol data is decoded and call information records (CIRs) are generated from the decoded signaling data. The CIRs contain information about calls associated with the telephone numbers. The CIRs are used to generate a report which is made available to the user.
