Chapter 10: Oracle Data Warehousing and Business
Intelligence
In addition to covering the database and data warehousing, this chapter describes
Oracle??™s current suites of business intelligence tools and business intelligence applications.
New features in the database for data warehousing include:
Database OLAP Option query rewrite and improved manageability
The OLAP Option is now refreshed similarly to materialized views, and the database
optimizer can transparently redirect SQL queries to the OLAP Option
stored summaries.
Binary XML
Performance of binary XML is up to 15 times that of XML LOBs stored in Oracle.
Partitioning enhancements
There are new composite types (list-hash, list-list, list-range, and range-range)
and a new partitioning type, interval partitioning, that automatically creates
range partitions as needed.
Data Mining Option enhancements
This option now provides generalized Linear Model algorithms and automated
data preparation.
