Among the specific topics considered within this course are:

• Understanding star and snowflake schemas and other data warehouse physical and logical database objects.
• Understanding and encouraging optimization of star queries.
• Creating and maintaining materialized views to enhance ad-hoc query performance against enormous volumes of transactional data.
• Manage materialized views to effectively and efficiently maintain their structure over the course of time.
• Creating and maintaining dimensions and hierarchies to enhance ad-hoc query performance and support sophisticated data mining.
• Performing dimensional analysis of data warehouse information and building cubes.
• Configuration of the Oracle Warehouse Builder (OWB) repository and consideration of OWB capabilities.
• Implementing data quality assurance using data rules and the OWB Data Profiler to evaluate data quality within transactional source databases and warehouse target databases.
• Using mappings and process flows for data correction and augmentation, as well as building Extraction, Transformation and Transformation (ETT) or Loading (ETL) processes within OWB.
