Federal Enterprise Architecture Framework and data middle platform technology and its application in sharing of atmospheric environment data resources

On the basis of reviewing the current status of scientific data management and sharing, the specification of environmental information sharing construction was analyzed, and the limitations of fine operational sharing were revealed. The content, composition and characteristics of US Federal Enterprise Architecture (FEA) Framework and the data middle platform technology were analyzed, and the feasibility of their application in exploration of atmospheric environmental data resources sharing methods was evaluated. FEA Framework, as the methodology for the construction of e-government information sharing in the United States, has the characteristics of serving business strategic development goals and implementing the shared assessments throughout the process. It can provide the methodology for industry shared data discovery, shared boundary characterization and shared performance evaluation. In recent years, data middle platform is a domestic enterprise-level data resource sharing application technology, which has the function of facing the overall development of the business. Through the establishment of a unified data governance system, it can meet the functions of data resource sharing, reuse, business demand response, etc. FEA Framework and data middle platform technology were used in the design of Beijing-Tianjin-Hebei region and Fen-Wei Plains atmospheric environmental data resource sharing, focusing on the key issues in the construction of data resource sharing such as data sharing inventory, data standardization and real-time business response, and the technical route was summarized. The practices showed that the realization path of atmospheric environment data resource sharing based on FEA Framework and data middle platform technology, namely “data asset discovery, data standardization, shared business agile processing”, could better achieve the goal of one-stop atmospheric environment data resource sharing, and meet performance assessment requirements.
