Re: How datas can be handled in Big database

The best way of handling your problem would be to use partitions. This will increase your query performance if you give the optimizer the chance to identify when only current data is needed to answer a query. You can further reduce backup time if you set the tablesspace of your "old" data to read-only whenever it is "frozen"
