With the continuous application and popularization of big data technology, all government departments are aware of the importance of data as a national basic strategic resource, and all over the country have been promoting the sharing and opening (SOA) of local government data (GA) one after another, improving the organization, formulating government regulations, and building a GA SOA platform. At present, GA are kept separately in each department, while there is no good DS scheme, resulting in low data sharing (DS), lack of authenticity of shared data, easy leakage of data, and difficulty in data tracking. Through the analysis of the above problems, an integrated platform(IP) of GA SOA based on big data is designed, aiming to realize safe and controlled sharing of GA. The application of this platform helps to efficiently integrate data resources and maximize the realistic value of GA for people's services in order to achieve sustainable social development.
