Improved optimization

Optimizer predictions for decision support operations are compared with actual results, and there will be subsequent adjustments in future predictions if indicated.

MODEL clause

This clause in the SELECT statement allows relational data in a query to be treated as a multidimensional array, which can also have formulas applied to them.

Cross-platform transportable tablespaces

Transportable tablespaces can be used to move data between different operating system platforms.

Downstream capture of change information

Change information can be captured from log files, rather than from the database.

Data Pump

This is a high-speed data transfer application.

Data mining enhancements

These enhancements include text mining and BLAST similarity searches.
