XML DB and Oracle Data Miner

Oracle Data Miner uses XML DB to store workflows in the Oracle Data Miner repository. XML DB is typically included in Oracle Database Enterprise Edition and is required for installation of Oracle Data Miner.

To determine if XML DB is present in the database, or to manually install XML DB, follow the instructions in Oracle XML DB Developer's Guide:

• Oracle Database 12.1: Oracle XML DB Developer's Guide

• Oracle Database 11.2: Oracle XML DB Developer's Guide:

Workflow documents in the Oracle Data Miner repository are of type XMLType, an abstract data type that provides these storage models:

• Object-relational storage – XMLType data is stored as a set of objects.

• Binary XML storage – XMLType data is stored in a post-parse, binary format specifically designed for XML data.

Oracle Data Miner uses object-relational storage in earlier versions of the Database and binary XML storage in later versions.
