Question

Difference between sequential and Random files organization​

Answer 1

(a) Random file organization method is faster because records are stored and accessed directly as opposed to sequential file organization method which is slower since records are read and written one after another in a sequential order.

(b) File update(deleting, adding or modifying records) in random file organization is faster than that of sequential method.

(c) In random file organization method, transactions need not to be sorted prior to update as the case of sequential files, that requires transactions to be sorted first before update.
