Basic study on the construction of a database in sedimentary petrology

1.通过对日本数据的调查表明，在沉积岩石学方面有许多数据，其中一些数据被收集并输入并提供给国际地球科学计划269.2。对IGCP 269提出的数据结构和数据表进行了分析。向国际地球科学计划269.3发送了对所描述的项目和表述的若干意见。原型数据库是在IBM/PC机上用Paradox和FoxBASE两个商用数据库管理软件，配合IGCP 269，输入实例数据建立的。它包含300多个数据和1.4MB，并与运行时版本的软件一起发布和分发。阐明了在将该数据库转换为日文版本时存在的两类问题：一是编程问题，二是软件本身的问题。前者得到了澄清，但后者尚未得到解决。本课题组对原型的数据结构、数据录入系统和检索系统进行了检查，并向IGCP 269报告。为了宣传该数据库，在第29届政府间大会、第13届CODATA会议等会议上报告和演示了原型数据库，并举办了培训班。作为我们研究的结果，有必要通过更新和扩展原型数据库来构建实际的数据库。在IGCP269最后一次会议(1993年6月，安卡拉)上决定提出一个新的项目来开发该数据库。

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).
