项目摘要

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).

1.通过对日本数据存在情况的调查可以清楚地看出，在沉积岩石学方面有许多数据，其中一些数据已经收集、输入并提供给了国际地球科学计划269.2。对IGCP 269提出的数据结构和数据表进行了研究。对所述项目和表述的若干意见已提交给IGCP 269.3。与IGCP 269合作，在IBM/PC机上使用两个商业DBMS软件（Parabel和Foxbase）并输入实例数据，建立了原型数据库。它包含300多个数据和1.4 MB，它与运行时版本的软件一起发布和分发。4.阐明了原型数据库转换为日文版的两类问题：一是程序问题，二是软件本身的问题。前者已被清除，但后者尚未得到解决。本课题组对原型的数据结构、数据输入系统和检索系统进行了研究，并向IGCP 269报告。为了宣传该数据库，在第29届政府间委员会、第13届CODATA会议等上报告和演示了原型数据库，举办了培训班。研究结果表明，有必要对原型数据库进行更新和扩展，以构建实际的数据库。已决定在IGCP 269最后一次会议（安卡拉，1993年6月）上提出一个利用该数据库的新项目。
