Administer a Data Warehouse
With Oracle Database

Visão Geral do Treinamento
  • This course will help you understand the basic concepts of administering a data warehouse. You'll learn to use various Oracle Database features to improve performance and manageability in a data warehouse.

  • Implement partitioning.
  • Use parallel operations to reduce response time.
  • Extract, transform and load data.
  • Create, use and refresh materialized views to improve 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 rewrites.
  • Identify the benefits of partitioning, in addition to using parallel operations to reduce response time for data-intensive operations.


  • Expert instructors will also teach you how to extract, transform and load data into an Oracle database warehouse. Discover how to use SQL Access Advisor to optimize the entire workload. Use materialized views to improve data warehouse performance and learn how query rewrites can improve performance.
