Extract of sample "The Sequential Access Files"

The sequential access files could either be in the form of a line sequential organization or indexed sequential organization (Brown, DeHayes, Hoffer, Martin, Perkins, 2009). What is most important is how the records are accessed. If these are accessed in the form of the sequential format, the sequence is maintained nonetheless but if this is done through a direct approach, there is no fixed mechanism behind the same. The direct access files are the ones which come about in a random fashion and are easily understood within the search mechanisms.

It is easy for the files to be found on the record because there is no order to this system which has been employed. Hence it becomes easier to access files in this fashion nonetheless. In the end, it is correct to state that both sequential access files and direct access files are significant towards the file organization hierarchies.
