What is the method of partitioning management in Oracle…

There are several methods for partition management in Oracle.

1. Range partitioning: partitioning based on the range of a column, such as partitioning by date range.
2. Partitioning by column: dividing data based on the values in a column, such as by region.
3. Column and Range Composite Partitioning: This method combines the techniques of range partitioning and column partitioning, allowing for partitioning based on the ranges and values of multiple columns.
4. Hash partitioning: Partitioning data based on the hash value of a column to ensure even distribution across different partitions, suitable for load balancing requirements.
5. Partition expansion: Splitting the partition key column into multiple columns to reduce the number of partitions and improve query performance.

Partition management can improve the performance and maintainability of the database, making it easier to manage and query data.
