Best Solution for Archiving Table data

Question

Hi All,
I have a table with huge data. It is not partitioned table.
On an average per day 10000 records will be inserted into this table. Now I want to archive(backup)
every one years data manually and keep in safe location and hence delete those archived rows
from the table. Whenever required it should be easily imported back to this table. All this happens through
Application.
One appraoch in my mind right now, is transferring the data from table to flat file with comma separted,
and whenever required again importing back to the table from Flat file using external tables concept.
Can any body suggest what is best solution for this.
Thanks

Answer 1

The best solution would be partitioning.
Any other solution requires DML - running DELETE and INSERT transactions to remove a data set and to add a data set (if need be) again.
With partitioning this is achieved (in sub-seconds) using DDL by exchanging a partition's contents with that of a table. Which means that after the archived data has been loaded (SQL*Loaded, Import, etc) into a table (and indexes created), that table (with indexes) is "swapped" into the partition table as a partition.
