Abstract

Concurrency control schemes are developed to improve the throughput in a shared database by providing mechanisms which synchronize operations issued by concurrently executing processes. In this paper, we present efficient algorithms for concurrent operations in two structures; namely Multi-dimensional Linear Hashing and Interpolation-Based Index Maintenance. Both of these structures are extensions of Linear hashing to the multi-dimensional case. The concurrent scheme presented is an adaptation of the one proposed for linear hashing. The algorithms include searching for, inserting, and deleting data elements. These algorithms support a high degree of concurrency and are shown to be correct based on the restrictions imposed by the compatibility scheme.
