Index-Organized Table (or IOT)
is a table that uses B-tree index structure for data storage.
They are different from heap-organized tables that keep rows in an unsorted order. IOT indexes maintains a primary key order and contain every column of the table. Hence, all rows can be accessed through logical rowid, instead of the physical rowid used in heap-organized tables.
