Based on the analysis of problems encountered in the development of statistic information system, statistic metadata is intro-duced to statistic information system to promote the standardization of statistics, and data loading model based on SDMX (Statistical Data and Metadata Exchange)standard is also proposed. Data loading model loads data from different business systems and external shared systems to a shared database according to a unified standard, integrating data from different data sources into one database. SDMX that is widely used in the world is introduced to the model, facilitating statistic data exchange and sharing internationally. The implementation of the model provides the guarantee of data for the statistic shared database.
