Why sorting and indexing are not one ?
by

1 Answer

Answer :

Sorting and indexing are not the same. This is because sorting the data file in the sorting method changes the serial number of the record in the original data file. But the serial number of the indexing record remains unchanged. Also, when a database modifies or adds a record, the sorted file is not updated , but the indexing is updated automatically. So sorting and indexing are not one.
