direct access method
A technique for finding data on a disk by deriving its storage address from an identifying key in the record, such as account number. Using a formula, the account number is converted into a sector address. This is faster than comparing entries in an index, but it only works well when keys are numerically close: 100, 101, 102, etc. See direct access.Copyright © 1981-2025 by The Computer Language Company Inc.
