What's New in Oracle Data Mining Administration?

This section summarizes the new features in Oracle Data Mining.

This section contains the following topics:

Oracle Database 11g Release 2 (11.2.0.2) New Features in Oracle Data Mining

In Oracle Data Mining 11g Release 2 (11.2.0.2), you can import externally-created data mining models when they are presented as valid PMML documents. PMML is an XML-based standard for representing data mining models.

The IMPORT_MODEL procedure in the DBMS_DATA_MINING package is overloaded with new syntax to support PMML import. When invoked with this syntax, the IMPORT_MODEL procedure will accept a PMML document and translate the information into an Oracle Data Mining model. This includes creating and populating model tables as well as SYS model metadata.

External models imported in this way will be automatically enabled for Exadata scoring offload.
