Therefore, the existing data models, whether it is an object model or a domain model, it is not the information of the real world, but the visualized parameters of some of its properties (basic, not completely).

To achieve this purpose, the Web ADF requires a public framework in which data sources can be integrated into the web ADF component. This framework is the universal data source API (Application Programming Interface ), or simply put, it is a general API.
