锰矿石可选性预测系统的研究——Ⅱ.锰矿石数据库设计

Study on the Prediction System of Manganese Ore′s Washability——Ⅱ.The Design of Manganese Ore′s Datebase

锰矿石数据库设计是在锰矿石可选性预测系统需求分析的基础上进行的。本着重介绍了锰矿石数据库的概念设计、实现设计和物理设计 ,并确立了锰矿石数据库的E -R模型 ,完成了关系模式的转换 ,建立了锰矿石数据库。

The design of manganese ore′s database is based on the manganese ore′s washability prediction system. The paper mainly introduces the concept design, implement design and physics design of the manganese ore′s database and establishes the E-R model of the manganese ore′s database. Furthermore, the relationship model′s convertion has been finished and the manganese ore′s database has been built up.
