Customizable Web Service for Effcient Access to Distributed Nuclear Physics Relational Databases
An increasing fraction of the data generated in Nuclear and High-Energy Physics (HENP) is managed in distributed and relational databases. As the size of this data grows and the collaborative nature of HENP experiments increases, the remote, efficient, and user-friendly access these differently-organized relational databases will become increasingly important. This project will develop a system for providing efficient access for the HENP data stored in distributed heterogeneous relational databases. The system will consist of a generic Web Service, customized client Application Program Interfaces (APIs), and tools that facilitate automatic generation of custom client APIs. Access to the data will be mediated by mechanisms that provide data caching and adaptive scheduling of query plans. Phase I will implement prototypes of these elements and concentrate on the needs of the STAR experiment at the Brookhaven National Laboratory. Commercial Applications and other Benefits as described by the awardee: The proposed system could be used in various virtual organizations where users need to access data efficiently from large distributed and heterogeneous relational database. Nuclear physics, high-energy physics, space science, bioscience, and climate modeling would greatly benefit from these tools. The system also could find use in business-to-business applications, where customers require easy and efficient access to distributed relational databases.
