· Oracle Partitioning divides large tables and indexes into smaller, manageable partitions.
· It is used to improve performance, scalability, and manageability of large database objects.
· Partitioning must be explicitly defined by the DBA; it is not automatic.
· Common partitioning types include Range, List, Hash, Composite, and Interval partitioning.
· Query performance improves through partition pruning, where only required partitions are accessed.
· Maintenance tasks such as backup, recovery, and data deletion can be performed at the partition level.
· Oracle Partitioning is available only as a licensed option in Oracle Enterprise Edition.
· Oracle supports both local and global partitioned indexes.
· Applications can access partitioned tables without any changes to application code.
· Partitioning is most effective for very large tables, especially those storing time-based or historical data.
