Integration and Comprehention of Databases Related to Disaster Science

这是一个研究小组为自然灾害科学准备数据库所做的成果。我们从1982年起建立了文件数据库SAIGAI，其中包括与自然灾害有关的文件数据，如研究论文、调查报告、在受灾地区拍摄的观测数据和照片清单、已公布的危险地图和航空照片索引地图清单、报纸上关于自然灾害的文章、政府和市政统计数据出版物。赛盖通过校际信息发布系统(N1系统)为您提供在线服务。FIRS是一款用来搜索数据库的软件，它为你提供了交互功能。这个数据库现在有45000个条目，定期更新，以提供对最近公布的关于自然灾害的信息的访问。日本自然灾害科学学会(JSNDS)信息处理委员会向文部省建议，通过扩大SAIGAI数据库，在5年内开发一个有10万个词条的文献数据库。在维护SAIGAI的过程中，我所继续讨论应该开发什么数据库。为了加深对自然灾害科学数据库系统化的认识，我们在JSNDS组织了一个工作组。经过两年的讨论，我们得出的结论是，正在开发的数据库应该是一个连接文档库、图像库和数值库的关系型数据库。推荐的数据库结构示例。第一部分存储每一次灾害的公共数据，另一部分与自然灾害科学的各个研究领域的数据相关。常用数据库包括数字化土地基础信息文献数据库、气象相关数值数据库、包括危险地图、航空照片和卫星数据在内的图像数据库以及与环境有关的数据库。

This the out growth of done by a research group to prepare a database for natural disaster science. We have developed the document database, SAIGAI,from 1982 which includes document data related to natural disaster such as, research papers, investigative reports, lists of observed data and photographs taken at disaster struck areas, lists of published hazard maps and index map of air photos, articles on natural disaster in newspapers, goverment and municipal publications of statistical data. SAIGAI provides you an online service through the inter-university information distributing system (N1-system). FAIRS,a software being used to search the database, offers you an interactive capability. This database which has right the now 45,000 entries is regularly updated to provide access to the most recently published information about natural disaster. Information-processing Committee in JSNDS(Japan Society for Natural Disaster Science)has recommended to the Ministry of Education to developed a document database with 100,000 entries in 5 years by expanding the database SAIGAI.In the process for maintaining SAIGAI,discussions about what databases should be developed have continued in our Institute. We have organized a working group in JSNDS to get a deeper understanding for systematizing databases related to natural disaster science.Through discussions for two years we have concluded that the developing database should be a relational database interconnecting document database, image database and numerical database.recommended shows a sample of database structure. First part stores common data for every disaster and the other part is related to data for each research field of natural disaster science. Common databases consist of document database of digitized fundamental land information, numerical database related to meteorology, image database including hazard maps, air photographs and satellite data, and database related to environment.
