Research and development of mobile geographic information system based on cloud computing Gao Guenyunlan in view of the current low transmission efficiency of mobile GIS and the limitation of large data processing, the paper introduces the Hadoop cloud computing platform and constructs the Mobile Information system based on the Hadoop cloud computing platform, and studies the workflow The difference between it and the current mobile Geographic Information system is analyzed. The experimental results show that the mobile geographic information system based on Hadoop has quicker response time than the existing system in service processing, and can solve the existing transmission efficiency to some extent.

Research and application of large data storage technology based on NoSQL database Sun Zhunting The amount of data collected and processed in the actual project is very large, which presents a great challenge to the traditional database technology. Aiming at the disadvantage of traditional relational database with slow storage speed and high hardware requirement, a large data processing method based on NoSQL database is proposed, which breaks the relational model of traditional database, and the data is stored in a free way, but not dependent on fixed table structure. This method mainly combines empirical mode decomposition and NoSQL database technology, and is applied to deformation monitoring of large structural parts.
