For example oyu have a huge table and you partition the table due to a date
field in it.
Think every 30 days will be a partition.
You created the table and inserted values for 1 year now you have 12
partition. and want to query the table for a specific day. Your query
sentence does not change but oracle only looks up the partition you are
interested in. This means 12 times faster full scans for this example.
