基于元数据管理的防腐蚀技术网络数据库设计

基于元数据管理的数据共享方式,参照Dublincore元数据标准体系,建立了符合防腐蚀技术数据管理的元数据标准体系,实现防腐蚀技术数据的元数据集中存储、集中管理,对录入数据进行严格的质量控制.采用ASP.NET技术,开发了Windows环境下的网络防腐蚀技术数据库查询系统.该数据库查询系统由6部分组成:产品零件防腐蚀设计库、工程结构防腐蚀设计库,材料自然环境腐蚀数据、腐蚀标准规范库、腐蚀失效分析库以及腐蚀知识数据库.系统所有数据资源可实现网络共享,用户可方便快捷地获得防腐蚀设计和控制方面的解决方案.

Design of Anti-corrosion Technology Database Based on Metadata Management for Internet

Based on metadata management,a new metadata standards system was founded which was suitable for anti-corrosion data according to Dublincore metadata standard,so the metadata of anti-corrosion could be stored and managed intensively and the quality of data could be controlled strictly.Meanwhile,based on the management system of SQL SERVER 2000,a network-based Anti-corrosion technology database system under Windows system was designed and established by using ASP.NET technology.The database system was made up of six parts: Anti-corrosion technology for products,anti-corrosion technology for engineering,corrosion data of materials in natural environment,corrosion standards,corrosion cases,and knowledge on anti-corrosion.The data of this system have been shared on the Internet,so the users can gain the solutions in the design and control of anti-corrosion conveniently.
