Abstract: The lack of unified planning for the construction and design of the existing meteorological system has resulted in a large number of systems, scattered, disordered and poor data management, weak overall safety protection capability and poor intensification. Using distributed technology, this paper constructs a hybrid model big data service center based on “distributed relational database+transactional database+columnar database+table system+distributed file system”, which stores, manages and serves data, and seamlessly connects with provincial CIMISS system through MUSIC interface, which effectively realizes data sharing and highly integrated process about, and greatly improve the ability of data impact. Under the same conditions, the performance of automatic station data query in 10 years has increased by more than 22 times, and with the increase of time dimension, the advantage of this improvement will be greater.

Key words: data sharing, distributed database, MUSIC, CIMISS, file storage
