REFERENCE DATA SEGMENTATION FROM SINGLE TO MULTIPLE TABLES

Embodiments of the present invention can be used to improve cross reference look-up performance by performing multi-table data segmentation. In accordance with an embodiment, a method of multi-table data segmentation can comprise augmenting each of a plurality of definition files associated with a database table with multi-table data. The method can further comprise creating a plurality of multi-tables. Each multi-table is associated with a different one of the plurality of definition files. The method can further comprise transposing data stored in the database table based on the plurality of definition files, and migrating the transposed data from the database table to the plurality of multi-tables.
