Performance Evaluation of a Two-Level Hierarchical Parallel Database System
free download

Abstract Two typical architectures of parallel database systems are the shared-everything and shared-nothing architectures. Shared-everything architecture provides better performance than the shared-nothing architecture but it is not scalable to large system

Dynamic action scheduling in a parallel database system
free download

This paper describes a scheduling technique for parallel database systems to obtain high performance, both in terms of response time and throughput. The technique enables both intra-and inter-transaction parallelism while controlling concurrency between transactions ABSTRACT Data mining from relations is becoming increasingly important with the advent of parallel database systems. In this paper, we propose a new algorithm for mining association rules from relations. The new algorithm is an enhanced version of the SETM algorithm [Set

Optimizing parallel access to the BaBar database system using CORBA servers
free download

Abstract The BaBar Experiment collected around 20 TB of data during its first 6 months of running. Now, after 18 months, data size exceeds 300 TB, and according to prognosis, it is a small fraction of the size of data coming in the next few months. In order to keep up with

Dynamic query processing in a parallel object-oriented database system
free download

Timely information has become increasingly important for today's competitive businesses. Furthermore, it has proven to be a valuable commodity. The number of information services or business relying on timely information is growing fast. It is reported that the data volume

A study of BNP parallel Task scheduling algorithms Metric's for Distributed database system

ABSTRACT To solve number of complex scientific problems one must require elevated computation rate comparable to supercomputer. The modernization in latest technologies, communication and information lead to the development of distributed systems and

addressable parallel processor (MW-OCAPP) for high-speed parallel relational databaseprocessing: architectural concepts and preliminary experimental system
free download

This paper presents a novel architecture for parallel database processing called Multi- Wavelength Optical Content Addressable Parallel Processor (MW-OCAPP). MW-OCAPP is designed to provide efficient parallel retrieval and processing of data by moving the bulk

Parallel Query Processing on a Cluster-based Database System
free download

Parallel Database Management Systems Databases have always been very important applications for any computing environment. Parallel databases share the advantages and disadvantages of parallel systems. The various parallel databases that have been developed, eg Bubba [BORA90], are not

Design and Modeling of a Parallel Database System
free download

Relational database systems are widely used as main data storage for current applications. These applications generate numerous data operations to the database system in a day. These operations include both simple transaction and complex data query. Each simple

The Requirements of a Database System for a Parallel Programming Environmentz
