Direct Organization:

Besides the relative or indexed organization, also a direct access file can be designed to have what is termed as direct organization.  In this organization, the data records are stored or "accessed" by using a scheme of converting the record into the disk address to which the record is placed. Therefore, no index table as in the case of an indexed file is essential.
