Organization refers to the way records are physically arranged on the secondary storage device. This may be either sequential or random. The records in sequential files are stored in contiguous locations that occupy a specified area of disk space. Records in random files are stored without regard for their physical relationship to other records in the same file. Random files may have records distributed throughout a disk.
The access method is the technique used to locate records and to navigate through the database or file. While several specific techniques are used, in general, they can be classified as either direct access or sequential access methods.
