Computer-implemented methods, apparatuses, and computer-readable media for generating a tier rollup record perform the steps of: receiving a request for one of a product record and a plurality of product records having a determined attribute value; querying a first data set for product records corresponding to the request; receiving one or more unique record identifiers corresponding to the request; querying a second data set for a product record and associated product attribute values corresponding to each unique identifier; receiving the product record and associated product attribute values corresponding to each unique identifier; identifying a most representative product record from the product records and associated product attribute values corresponding to each unique identifier; rolling up the most representative product record; and transmitting the rolled up most representative product record.
