What Is File Organization?

What are the differences between sequential file organization and direct file otganization?

• Answer:

  A sequential file is accessed one record at a time, from first to last, in order. Each record can be of varying length. A direct (or random) file is accessed in any order, by record number. Each record must be of identical length. A sequential file might look like this, with records separated by commas: bear,skunk,moose,fish,alligator A direct file with the same data would look (something) like this: bear_____skunk____moose____fish_____alligator
