The Design and Realization of the Material Series Database System

材料体系由多层体系结构和最底层的材料牌号数据构成。为构建材料体系数据库系统,针对材料体系的多层数据结构、数据特征、层次之间的内在联系、多层结构与材料牌号及其性能数据的关系开展了深入研究。设计了材料体系数据库和牌号性能数据库的逻辑结构与物理结构,应用 Oracle 和 J2EE 开发设计了软件系统,实现了从体系结构到牌号性能数据的无缝连接。对整个材料体系的多层结构,文本、图片、表格等多种数据实现了有效管理和直观显示。

The Design and Realization of the Material Series Database System

Aiming at the special material equipment,a multi-layer database structure was studied.The data characteristics,the intrinsic relationship of each layer,and the multi-layer database structure related to the material trademark and its performance were defined.The logical organization and the physical structure of the material series database and the material performance database were designed,as well as the software system was developed based on the Oracle and the J2EE technology.The data exchange between the two databases of the material trademark and the performance can be seamlessly connected,which shows that the system can effectively manage and intuitionisticly display the material series framework and detail information with text,picture,forms and so on.
