Data Dependence: In computer file-based processing systems, the data
stored in file depends upon the application program through which the file was
created. It means that the structure of data files is coupled with application
program. It is difficult to change the structure of data files or records. If
you want to change the structure of data file (or format of file), then you
have to modify the application program.
