Перевод традиционная таблица
Описание An ordinary table whose data is stored as an unordered collection (heap). For a normal (heap-organized) table, moving a row changes that row?s rowid. For a moved row in an IOT, the logical rowid remains valid, although the physical guess component of the logical rowid becomes inaccurate. See index-organized table (IOT).
