The disclosure discloses a mimetic database-based network operating system design method, including: designing a mimetic data structure; designing a mimetic data object; designing a synchronization mechanism and a decision mechanism, designing a mimetic database safe storage command processing system, and designing a classification storage mechanism for interacting data between service modules and a master database in a network operating system. By means of vertical hierarchy and horizontal classification, the problem of compatibility of the database subjected to mimetic transformation and a network operating system is solved. By means of a memory random distribution storage mechanism and a memory hardware heterogeneous storage mechanism, the cost caused by mimetic transformation can be reduced, and the cost is controllable while the safety is improved.
