Oracle Database 11g: Administer a Data Warehouse

Duration: 4 Days

What you will learnParticipants learn about Oracles Database partitioning architecture and how to identify the benefits of partitioning inaddition to using parallel operations to reduce response time for data-intensive operations. Participants extract,transform, and load data into an Oracle database warehouse. Participants also use materialized views to improve thedata warehouse performance and learn how query rewrites can improve performance.

The usage of SQL Access Advisor to optimize the entire workload, tuning materialized views for fast refresh and queryrewrite and also how to use the compression and resumable sessions features are discussed.Learn To:

Implement partitioning Use parallel operations to reduce response time Extract, Transform, and Load data Create, use, and refresh materialized views to improve the data warehouse performance Use Query rewrite to quickly answer business queries using materialized views Use SQL Access Advisor and PL/SQL procedures to tune materialized views for fast refresh and query rewrite
