Abstract

A plurality of data records is provided, each data record having paired keys comprised of a first key and a second key. The first key identifies each data record in a certain manner and the second key identifies each data record in a different manner. The paired keys can be used to for example, by the first key identifying the original business identity which the data record belongs to, while the second key may identify the current business identity which the data record belongs to. In this way pre-merger data, for example, and post merger data can be retained. In one embodiment an apparatus is provided comprising a first table of data records and a second table of data records. The tables of data records may be stored in a computer memory. Each first table data record may correspond to an entity and may be comprised of a first field having a first set of data identifying a first characteristic of the corresponding entity, a second field having a second set of data identifying a second characteristic of the corresponding entity; and a third field having a third set of data identifying a third characteristic of the corresponding entity. Each second table data record may correspond to an entity and each second table data record may be comprised of a fourth field having a fourth set of data identifying a fourth characteristic of the corresponding entity. Each fourth set of data of each data record of the second table of data records may have a corresponding first set of data in a data record of the first table of data records, which is substantially the same, for the same entity.
