Optical parallel database management system for page oriented holographic memeories

Parallel data detection in page-oriented optical memory.

We discuss a novel two-dimensional parallel technique for reliable data detection in page-oriented optical memories. The method is motivated by decision feedback techniques and is fully parallel, offering convenient, locally connected electronic implementation. The algorithm is shown to offer significant improvements over simple threshold detection and in some cases can approach the maximum-lik...

Page Replacement Algorithm for Buffer Management in the Omega Parallel Database System

This paper introduces a new approach to database disk buffering, called the LFU-K method. The LFU-K page replacement algorithm is an improvement to the Least Frequently Used (LFU) algorithm. The paper proposes a theoretical-probability model for formal description of LFU-K algorithm. Using this model we evaluate estimations for the LFU-K parameters. This paper also describes an implementation o...

Parallel Database Management System: Kappa

A parallel database management system (DBMS) called Kappa is developed in order to provide e cient database management facilities for knowledge information processing applications. The data model of Kappa is based on a nested relational model to treat complex structured data e ciently. The system is written in KL1, and works on parallel and/or distributed environments of conventional machines w...

Object Oriented Database Management System for Decision Support System

To get best performance for an analytic system or data warehouse systems, two technologies, column oriented database management systems and main memory database management system can be combined to get advantages of these two. Both technologies give best performance to its opponent database system, for example Main memory database management systems are faster as they reside in main memory as c...
