Oracle Database 11g: Data Warehousing and Oracle Warehouse Builder

Course:  OR11DWB
Duration:  5 Days
Level:  III
Course Summary

This course focuses on the features within the Oracle database that support data warehouses and data mining operations. The students will learn about data warehousing concepts and the requirements to initially configure a data warehouse installation. They will also learn how the Oracle Warehouse Builder (OWB) product may be used to implement and maintain both transactional and warehouse databases, and the movement of data between those two different types of installations.
