地震学情报数据库研究

A RESEARCH ON SEISMOLOGICAL INFORMATION DATABASE

摘要:

将国内出版的地震学期刊论文,建立一个联机检索数据库。使用VAX11/750小型计算机和VAX DTR、CDD软件,操作系统是VAX/VMS。地震期刊论文数据库分成二个数据库,题录数据库和论文文摘数据库。它们是文件结构型数据库。一条题录记录占339字节,一条论文文摘记录占1290字节。自行编制设计了人机对话式联机检索程序。用户使用感到十分简便。论文追溯时间计划为十年或更长一些。

Abstract:

Establishing an on-line retrievable journal paper database of seismology, these journals are published in China. Using VAX11/750 mini-computer, its operation system is VAX/VMS and VAX Datatrieve, VAX Common Data Dictionary software products. There are three file-structured databases, domain names are Papers, Subject Abstract, in this journal paper database of seismology. A record of Papers, Subject, Abstract is 1500, 225, 1281 bytes long, respectively. on-line retrieval programs are interactive mode, designed by myself. They are convenient to users.
