Data processing method, device and system

The embodiment of the invention provides a data processing method, device and system, logic relations between objects of a neural network are respectively stored in a data management module and a file storage module, on one hand, the logic relations between the objects are stored through a tree structure, so that hierarchical relations between the objects are reserved, and therefore, different permissions can be set for different objects based on the hierarchical relationship between the objects, and the flexibility of permission setting is improved; and on the other hand, the model file is flatly stored in the file storage module in an object storage mode, so that the model file can be efficiently accessed. According to the scheme of the embodiment of the invention, the flexibility of authority management and the efficiency of file access are both considered. 本公开实施例提供一种数据处理方法、装置和系统，将神经网络的对象与对象之间的逻辑关系分别存储在数据管理模块和文件存储模块中，一方面，对象之间的逻辑关系通过树形结构存储，从而保留了对象之间的层级关系，以便于基于对象之间的层级关系为不同的对象设置不同的权限，提高了权限设置的灵活性；另一方面，模型文件本身通过
