| Abstract: | The database used in structural repair support system for civil airplane is researched.In order to repair structural damage in civil airplanes timely and effectively,database is used to manage data in the process of structural damage assessment and repair decision.In the process of implementation,according to the system flow,system structure and logical structure of database are designed,integrity constraint and authority management are used as well,which ensure the security of database and accuracy of data.Besides,with the ADO.NET technology,connecting to the database and operating data are applied.The application of each database in the system is analyzed as well. |
