Oracle Database 11g: Administer a Data Warehouse training explains how to extract, transform and load data into an Oracle database warehouse. The training explains the basic concepts of administering the database, increasing the manageability, and improving the performance of the data warehouse. The expert professional will explain and provide you hands-on session on the optimized way of using the SQL Access Advisor for managing the entire workload.

By the end of the Oracle Database 11g: Administer a Data Warehouse training, you will be proficient in the following skills:

  • Learn data warehouse architectures, design, objects, and schemas
  • Implement partitioning and parallel operations to reduce response time for data-intensive operations
  • Extract, Transform, and Load data in the data warehouse
  • Work with Dimensions, hierarchies,and privileges
  • Create, use, and refresh materialized views to improve the data warehouse performance
  • Use SQL Access Advisor and PL/SQL procedures to tune materialized views for fast refresh and query rewrite that ultimately results in increasing the response time for answering business queries
Target audience
