Unindexed table or Heap. Microsoft Press Books and Book on
Line (BOL) refers it as Heap. A heap is a table that does
not have a clustered index and, therefore, the pages are not
linked by pointers. The IAM pages are the only structures
that link the pages in a table together. Unindexed tables
are good for fast storing of data. Many times it is better
to drop all indexes from table and then do bulk of inserts
and to restore those indexes after that.
