Patent ID: 8498917

Claim:
A method for computing a migration and performance matrix using a data processing system, the method comprising: receiving, by a processor, a selection of rated entities from a user; retrieving, by the processor from a database, mass data for the selected rated entities for a rating period; creating, by the processor, a first base matrix based on ratings and utilizations for the selected rated entities for the rating period; receiving at least one of an inflow or an outflow status for the selected rated entities; storing the received status in the first base rnatrix; forming, by the processor, a second base matrix based on the first base matrix; forming, by the processor, a plurality of additional matrices based on the second base matrix; arranging, by the processor, the additional matrices in an order according to one or more fields of the additional matrices; and generating, by the processor, the migration and performance matrix by combining the additional matrices in the order.
