Can you think of techniques other than an unordered overflow file that can be used to make insertion in an ordered file more efficient?
What will be an ideal response?
It is possible to use an overflow file in which the records are chained together in a manner similar to the overflow for static hash files. The overflow records that should be inserted in each block of the ordered file are linked together in the overflow file, and a pointer to the first record in the chain (linked list) is kept in the block of the main file.
The list may or may not be kept ordered.
