数据库的设计不仅要考虑全面反映具体情况的数据内容,而且要考虑存储、查阅和使用上的方便,以利于建立咨询、应用软件。本文介绍一个以工业环境为背景的腐蚀材料数据库结构及其应用程序原型的设计方法。数据结构采用腐蚀数据中心[由美国腐蚀工程师协会(NACE)和美国国家标准和技术研究院(NIST)共同创立]的标准格式,程序提供方便的数据输入、输出、修改、增删以及检索等功能。另外,用户还可以根据不同目的,对数据库进行访问和查询。

Designing a corrosion database needs to give comprehensive considerations to not only the data inputs to represent the overall conditions,but also the users' conveniences to input,output and access corrosion data,so that the application and consultation programs can be developed flexibly. A prototype of database program for corrosion of materials in industrial environments has been developed. The data structure of the corrosion database and the design method of the application program are introduced in this prper. The standardized data formats of the Corrosion Data center established by National Association of Corrosion Engineers (NACE)and National Institute of Standards and Technology (NIST) are adopted. The program permits easy data input,output,modification,addition,deletion and data selection. In addition, users can retrieve and access the corrosion data according to different purposes.
