Reordering Columns and Rows in Oracle For Demantra Performance Improvement
Columns and Rows in an Oracle table are not necessarily stored on the disk in primary key (consecutive) order.
Due to the way the Oracle RDBMS stores data physically on disk, it is possible to reduce storage and improve performance by rebuilding large tables that have many NULL-value or empty columns, to the end of the row. This is known as reordering.
