All of these products are being phased out by Oracle in favour of the Oracle Enterprise Data Quality product from the acquisition of Datanomic a few years ago. OEDQ is the strategic data quality offering, comprising fully integrated profiling, parsing and standardization, address verification, matching and merging for all data types. It can be bought with different configuration options. It includes a pack of pre-configured customer data services for matching and address verification that is pre-integrated with Siebel (CRM and UCM).
Documentation is available for both products. The EDQ documentation is here.
