Specialized External Tables
Big Data SQL gives users a single location to catalog and secure data in Hadoop and NoSQL systems: Oracle Database.
Seamless metadata integration and queries which join data from Oracle Database with data from Hadoop and NoSQL databases.
Automatic Mappings and Access
Utilities and conversion routines support automatic mappings from metadata stored in HCatalog (or the Hive Metastore) to Oracle Tables. Enhanced access parameters give administrators the flexibility to control column mapping and data access behavior.
Multiple cluster support enables one Oracle Database to query multiple Hadoop clusters and/or NoSQL systems within a single query.
