Learn To:

• Apply partitioning strategies to enhance application performance.
• Use partitioning techniques to reduce impact of table and index maintenance.
• Use partitioning to decrease the time to refresh materialized views.
• Partition lob segments, nested tables and object tables.
• Reduce risk of data exposure using Oracle Advanced Security Data Redaction, Transparent Data Encryption and Oracle Data Masking.
• Understand the Oracle Partitioning methods for tables, index and materialized views available in Oracle Database 12c Release 1.

Taking this course will introduce you to several new partitioning enhancements, including partition maintenance operations on multiple partitions, heat maps, partial indexes for partitioned tables, interval-reference partitioning and online move partition capabilities. When the new enhancements are added to all the existing methods of partitioning, this large range of choices and capabilities requires that database administrators and data architects understand each partitioning method and it's appropriate uses. Proper use of partitioning can greatly benefit many types of applications including data warehouses, information life cycle management and very large databases.
