Building the new countryside construction database plays an important role in improving the construction efficiency, and enhancing the level of major project management. On the basis of detailed analysis of features of the new countryside construction data, we give an overview of the database design based on ArcSDE and SQL Server, and elaborate the association between data classification organization, database conceptual design, logical design, spatial data, and thematic attribute data. Finally, taking the provincial new countryside demonstration zone in Yanjiang District of Sichuan Province for example, we build the new countryside construction database.
