Application of the Background Management Model to Data Sharing Service Platform
-
摘要: 为了使气象科学数据共享平台的运行逐步向自动化和业务化管理方向发展,基于元数据技术,建立了有针对性的后台管理模式,设计和开发了气象科学数据共享服务平台后台管理系统。该文介绍了当前信息系统发展的特点,分析了后台管理系统建设的业务需求,重点描述了系统的结构设计和元数据设计。共享平台的后台管理系统划分为数据层、管理层、服务层和保障层等4个结构层次,由元数据管理、业务管理、平台管理和系统监视等4个部件构成。系统采用J2EE的架构,保障了系统的可扩展性和灵活操作,实现了元数据管理、数据 (集) 管理、信息统计、内容管理、安全管理、系统配置管理和运行监视等功能。后台管理系统的部署和实施使新数据产品的发布更加便捷,也更具有时效性,保障了气象科学数据共享平台的平稳和安全运行。Abstract: Along with the development of meteorological data sharing service platform and the establishment of the security system, appropriate administrative organization and operating mechanism, a background management system is needed to realize automated and operational management. The background management model is planned as enriching the service data products and enhancing the quality of data service. A lot of developing work has been carried out to optimize the flow of data publishing and updating, operation flow, data automatic collecting, the whole network monitoring and data service to meet these demands and changes from the beginning of 2006. At the end of 2009, the construction of the whole data sharing platform is accomplished, which consists of foreground interactive sub-system and background management sub-system. The former is responsible for the provision of data discovery and data access, and the latter offers a lot of configure management functions.The background management system for meteorological data sharing service platform is developed completely based on the metadata technology, and it uses J2EE architecture to ensure the scalability and flexibility. The logic diagram of the background management system includes data level, management level, service level and support level. The system is made up of metadata management, operational management, platform management and system monitoring modules. The system realizes metadata management and new data product publishing, data (set) management, information statistics and analysis, content management, security management, system configuration management, system monitoring, and other functions. The deployment and implementation of background management system make sure that the publishing of one new data products become more timeliness and convenient, and ensure a long-term and stable operational running of the meteorological data sharing service platform.
