Abstract

The goal of the research on hashing as an access method is to arrive at a simple file organization scheme which guarantees single access retrieval from secondary storage, and is dynamic (can gracefully accommodate varying file sizes). There has been much progress in recent years in this regard. The Signature Hashing scheme for external files, proposed by Gonnet and Larson, guarantees single access retrieval [GL88]. But the scheme is static and implementation is complicated [LK84]. In this paper a simple external hashing scheme which guarantees single access retrieval is proposed and performance investigated. The scheme is dynamic, and its cost is better than that of Signature Hashing. An overview of the current state of the art and open problems are mentioned.
