Hashing Indirect Address Translation

Hashing Indirect Address Translation. Chapter 11. Indirect Address Translation. Direct translation Primary Key (PK) and the relative record position (RRP) are the same, we say there is a direct translation. Simple direct access file systems use this technique. Indirect Address Translation.
