The embodiment of the invention provides a method for establishing an attribute access. The method includes the steps of obtaining all attributes included in classes in a data model, and establishingan association relationship between each of all the attributes and at least one attribute feature. By means of the method, a data model object can quickly and easily acquire the self-defined capability for the attribute access, multiple data sources can be accessed with low cost, the development cost of writing data storage codes is reduced, the code quality and maintainability are improved, and the engineering invasiveness is low. In addition, the embodiment of the invention also provides a medium and device for establishing attribute access and computing equipment.
