Aim of this work
Charged particle reactions in Japan are complied by JCPRG
The complied data are formatted as NRDF
The charged reaction data are important, not only for
nuclear physics, but also for enginnering, medication,and other research fields related to nuclear reactions

Therefore, in this work
We support to utilize NRDF
in the view point of Information technology

We develop a system for data retrieving
3

based on the SQL-server and client scheme

Outline of the system
1．To provide data easily and widely
Server and client scheme
2．To support for utilizing data
Develop application for specific uses
Construct a PostgreSQL-database system
for NRDF by using the Perl script
Data search and utilizing application
driven by Perl/CGI5

Why the SQL-database for
NRDF is necessary?
Problem and difficulty
We need to handle the files themselves⇒ Data retrieving by “query” requests
z No-restrict formatz⇒ Format are fixed restrict in DB

NRDF
D1800-D2080

Perl

PostgreSQL

Solution for these problems

Construct the PostgreSQL-databaseby using the perl script9Perl/CGI

Summary and Discussionz The PostgreSQL-besed server and client system

for NRDF is developedz The system is suitable for utilizing data much morethan the ordinary text-based search system.
z For Hi-performance data retrieving and using usefulfunctions, e.g. making index, one need morecomputer power (faster, larger, and mulｔi-pipe)
