Abstract: The transformation of digital technology has continuously pushed the traditional manufacturing industry to become digital and intelligent. As a high-end manufacturing industry, the civil aircraft industry has a long development cycle, complex business, and extremely high requirements for supplier collaboration. The digital transformation of the civil aircraft manufacturing industry is a historical opportunity to lead the country's manufacturing industry to the forefront of the world. Data is the core of digital transformation and the core asset of an enterprise. Taking an aircraft manufacturing enterprise as an example, according to the characteristics of civil aircraft manufacturing industry, the design framework of hybrid cloud data architecture is given. The business model is obtained from the domain modeling led by business requirements, and the data model and microservices are independently developed based on this, and the hybrid cloud data architecture is designed to form a complete closed loop with clear requirements, reasonable business split, and light and fast service development and deployment. Under this data structure, 13 types of problems and 12 core subsystems were initially managed for data, and 6 databases, 9900 table objects and other data assets were obtained, and the governance effect was obvious.

Key words: civil aircraft manufacturing, digital transformation, hybrid cloud, data architecture design, data governance
