What are the different types of partitioning in Oracle databases?

There are several types of partitioning in Oracle database.

1. Range partitioning is the division of data into separate partitions based on the range of values in a specific column. For example, data can be partitioned into different sections based on dates.
2. List Partitioning: Partitioning data based on discrete values in a column. For example, data can be partitioned into different partitions based on geographic location.
3. Hash Partitioning: Data partitioned based on the hash value of a particular column. For example, data can be partitioned into different partitions based on user ID.
4. Composite partitioning combines range partitioning with hash or list partitioning. For example, data can be partitioned initially by date range, and then within each range, further partitioned by user ID using hash partitioning.
5. Custom partitioning: Partitioning based on the partitioning method of another table. For example, partitioning the order detail table based on the partitioning method of the order table.

Each partitioning method has its own suitable scenarios and advantages, and the appropriate partitioning method can be chosen based on specific needs.
