In the layered architecture of a website, there are three common layers, namely the application layer, the service layer, and the data layer. The application layer is specifically responsible for the display of business and views; the service layer provides service support for the application layer; the database provides data storage access services, such as databases, caches, files, search engines, etc. The hierarchical architecture is logical.
