Oracle Data Integrator (ODI) achieves data integration through an E-LT (extract, load, transform) model. You can use ODI to help with your cross-referencing needs. ODI provides three Knowledge Modules for handling SOA cross references that perform the following functions: Populate the cross-reference table, create a common ID for the target table, push the common ID and the source primary key to the cross-reference table, and create and push a unique row number that creates the cross reference between the source primary key and the common ID. With the modules, you can create an integration interface that both loads a target table from several source tables and handles cross-references between one of the sources and the target.
