Patent ID: 7640198

Claim:
A system for displaying a transaction table including at least one index, useful in association with price modeling and useful in association with a data source, the system comprising: a database configured to store transaction data, including price modeling data, from the data source and dynamically store changes to the transaction data, including price modeling data, from the data source, and further configured to provide client configuration of the data source, wherein the client configuration includes at least one calculation parameter and at least one mapping parameter and wherein the price modeling data depends upon the client configuration; at least one server coupled to the database over a network and configured to: request the transaction data including price modeling data from the database via the network, wherein the transaction data is requested in accordance with the at least one mapping parameter; populate the transaction table with the price modeling data; calculate at least one index base using the price modeling data populated in the transaction table, wherein the at least one index base is the denominator of the at least one index, and wherein the at least one index base is calculated according to the at least one calculation parameter; identify at least one index numerator from the price modeling data populated in the transaction table, generate the at least one index by dividing the at least one index numerator by the at least one index base, wherein the at least one index is a summary measure stating relative comparisons between groups of related items; dynamically update the at least one index in response to changes in the price modeling data; configure the transaction table to include at least one index column and load the at least one index into the at least one index column; a display coupled to the server and configured to display at least one of the at least one index in the transaction table, and wherein the display is also configured to display a limited subset of the transaction table, where the subset is selected by a zoom function.
