-dimensional abstraction factory is used. One is the database choice and the other is the table choice. The abstract factory can be used to conveniently select the database, you only need to change the content in the configuration file, and do not need to change other places. This reflects the principle of open and closed. The idal layer is responsible for placing interfaces. Public interface iuserinfo 'q
