The full life cycle test data of civil aircraft, as an important component of reflecting test information, can provide a basis for supporting the quality and efficiency of model development. However, due to the characteristics of large data volume and multi professional integration, the lack of integrated management leads to waste of data resources. A test data management business process based on airworthiness clauses has been proposed to control the testing data of multiple professional civil aircraft, and a database has been designed and implemented based on this. Firstly, conduct a demand survey on the technical center researchers and analyze the database functionality based on the survey results. Afterwards, based on the specific business requirements for storing multi-disciplinary test data and a comparison of market related database development technologies, an architecture design was carried out, and the logical relationships between the storage contents of each test module were sorted out. Taking the flight module as an example, the database module design was carried out. Finally, a database operation interface was built to verify the feasibility of the design, providing reference for the design of multi professional experimental databases.
