Oracle: Interval partitioning and dependant tables
You can't use interval partitioning with reference partitioning, however, It's possible to mix range partitioning and reference partitioning, as shown in the example of reference partitioning in the 11g doc:


  The benefit of this extension is that tables with a parent-child relationship can be logically equipartitioned by inheriting the partitioning key from the parent table without duplicating the key columns. The logical dependency also automatically cascades partition maintenance operations, thus making application development easier and less error-prone.


The child table doesn't need to contain the partition key (here the log date). It inherits the partition key from the parent table.



Range partitioning involves a bit more maintenance because you have to create the partitions  yourself. However, once the partitions are created, range and interval work similarly.
