The government affairs system based on big data technology is an advanced stage in the development of e-government. In this stage, with the help of big data platforms in the information age, through the large-scale use of modern communication equipment and the Internet, a new government management mode and management thinking are created, and then through the above way to promote information sharing. The connotation of intelligent government is information sharing, reducing government departments' office threshold to achieve information transparency and openness. Based on the above background problems, this paper analyzes the current government information management problems and the lack of resources sharing, and the problems existing in the concept of government personnel. On this basis, the current government system is analyzed. The feasibility and demand analysis of the current government system is put forward from engineering thinking to pave the way for designing the next GDRSAS(government data resource sharing application system). Finally, the design and construction of the GDRSAS are carried out, and in-depth analysis is carried out. The system can make more reasonable sharing application of government resources information under significant data background.
