Processing Relative Files
Roger Hutty, Mary Mikell Spence · 1997
Relatively organised files can be accessed sequentially in the same way that sequentially organised files can be accessed. The processing which was performed on the sequentially organised files in the previous chapter can also be performed on relatively organised files. However, relatively organised files have the advantage that they can also be accessed randomly, that is, a specified numbered record can be accessed directly in a relative file without having to search from the start of the file.
