Basic study on the construction of a database in sedimentary petrology

1. 对日本现有资料的调查表明，日本的沉积岩石学资料较多，其中部分资料已收集并输入IGCP 269.2。对IGCP 269提出的数据结构和数据表进行了审查。对所述项目和表述的若干评论已提交IGCP 269.3。与IGCP 269合作，在IBM/PC上使用两种商业DBMS软件（Paradox和Foxbase）并输入示例数据构建原型数据库。它包含300多个数据，1.4 MB，并与运行时版本的软件一起发布和分发。澄清了在将原型数据库转换为日文版本时存在的两类问题；一个是编程问题，另一个是软件本身。前者已得到解决，但后者尚未解决。本课题组对样机的数据结构、数据录入系统和检索系统进行了测试，并向IGCP 269报告。为推广数据库，在第29届IGC、第13届CODATA大会等会议上报告展示了原型数据库，并举办了培训课程。根据我们的研究结果，有必要通过对原型数据库的更新和扩展来构建实际数据库。在IGCP269最后一次会议（1993年6月，安卡拉）上决定提出一个利用数据库的新项目。

1. It was clarified by the survey of data presence in Japan that there are many data in sedimentary petrology, some of which were collected and entered and supplied to the IGCP 269.2. The data structure and data sheet, which were proposed by the IGCP 269, were examined. Several comments on described items and expression were sent to the IGCP 269.3. In cooperation with the IGCP 269, the prototype database was constructed using two commercial DBMS softwares (Paradox and Foxbase) on IBM/PC and entering example data. It contains more than 300 data and 1.4 MB, and it was released and distributed with the software of runtime version.4. Two kinds of problems were clarified in converting the ptototype database into the Japanese version; one is programing problems, and the other is in the software itself. The former was cleared, but the latter has not yet been solved.5. Data structure, data entry system and retrieval system of the prototype were examined in our group, and reported to the IGCP 269. To publicize the database the prototype database was reported and demonstrated in the 29th IGC, 13th CODATA Conference, etc., and training courses were held.6. As the result of our study, it is necessary to construct the actual database by updating and extending the prototype database. It was decided to propose a new project to exploit the database at the final meeting of IGCP269 (Ankara, June 1993).
