面对海量和离散的材料腐蚀数据，构建一个材料数据共享平台成为科学研究材料腐蚀性能的关键。本文所建平台基于平台引擎，利用基于可扩展标记语言的元数据驱动的思想实现异类、异构数据的统一存储和转换，利用智能Agent和中间件技术实现对异种数据库的通用管理和操作，利用基于角色的访问控制方法实现用户的安全管理，利用“应用层-综合层-转换层-数据层”四层授权机制实现对数据的安全管理，并通过演示系统证明了平台构建方案的可行性。整个平台框架具有较强的共享性、安全性、扩展性和开放性。
In order to utilize effectively massive and discrete materials corrosion data, a data sharing platform of material corrosion is proposed for scientific research. It is based on platform engine, and adopts Meta Data driven based on XML（extensible markup language） to implement the unified storage and conversion of different structures, types of materials corrosion data. Intelligent agent and middleware technologies are used to management and operation the heterogeneous databases. The user-role-privilege is adopted to implement user's security management. The four-layer architecture including application layer, integration layer, transform layer, and data layer is used to implement data security. A demo system is used to prove the feasibility of platform. The platform has characteristics of sharing, security, scalability and openness.
