Description

For obtaining the basic material to design database of space experiments, Japan Space Utilization Promotion Center has investigated the information sources, the current database services and requirements of users in space science. According to the citation analysis the existing information sources are centralized, and their lifetime is consideraly short. The survey on commercial databases show that Aerospace Database covers almost all of the document information, and JICST File as Japanese-text database has relatively wide coverage. The scope and growth of the conventional database services were estimated. It is concluded that the possible future database will not grow to large scale but have multi-files. Also an attention should be paid to complex data structure instead of data volumes. The report is intended to introduce survey methods for database building.
