scratch disk is used as a temporary space while performing operations like lookup,join,sort when the data volumne is big and the internal memory is not sufficient to hold the complete data during these operations
Guys,Please correct me if i am wrong.

I did think of a real groaner of an answer - an extended pun on the word "itch" - but decided not to go with it.
(It involved ITCH as an acronym.)
