摘　　要：为了整合太原地区分散的科学数据资源,运用软件架构和Web Service技术,设计了太原地区科学数据共享平台,该平台包括门户层、共享业务层、核心服务层、资源管理层和网络平台层。数据中心采用"数据超市"理念进行功能组织;分中心基于Web Services技术,采用分布式数据管理的模式进行设计。两者的业务逻辑基于元数据的生命周期被串联成一个有机的整体。原型系统利用J2EE开发,实现跨平台部署。应用实践表明这种平台构架模式非常适于构建区域科学数据共享平台。As one of the experiment units of the Shanxi Province Scientific Data Sharing Program launched in 2006, the Taiyuan Science Data Sharing Network （referred to as TYSDS） provides basic data services for research. Through the application of software architecture and Web Service technology, it is designed as a platform of distributed five-story structure, namely website portal , sharing business tier, the core services tier ,the data resource management and network platform tier. Driven by user requirements, the general center＇s functions are designed as a “data supermarket”, and they are developed through metadata techniques. Distributed sub centers are developed by Web Services techniques. All the function modules between general center and sub centers are organized according to the life cycle of metadata in the data sharing business. The TYSDS prototype system is developed with the cross platform program and applied within the Taiyuan Scientific Data Sharing Program.
