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 the face of massive and discrete material corrosion data, building a material data sharing platform has become the key to scientifically study the material corrosion performance. Based on the platform engine, the platform built in this paper implements the unified storage and transformation of heterogeneous and heterogeneous data by means of metadata-driven idea based on extensible markup language. The intelligent agent and middleware technology are used to realize the common management and operation of heterogeneous databases. Based on the role of access control method to achieve the user’s security management, the use of “application layer - integrated layer - the conversion layer - data layer ” four levels of authorization mechanism to achieve data security management, and through the demonstration system to prove the feasibility of platform construction program Sex. The entire platform framework has a strong sharing, security, scalability and openness.
