To satisfy the needs of space-ground integrated network visualization, establish the database system platform based on MySQL. Through the analysis of the structured data composition and characteristics of space-ground integrated network, design entity relationship diagram (E-R) and data table of node data, link data and network data successively to build the structure database of space-ground integrated network. User management, data management and maintenance are realized through MySQL Workbench software. The database provides strong data support for the follow-up visualization research on the integration of space-ground integrated network.
