Web interface design

First of all, you have to see whether the webpage you write calls or uses hardware (peripherals such as short message cats) and other software (including the interface of the database). For all the parts you use that are not developed by yourself, you must call others or let others call your own methods to abstract this into an interface, that is, write clearly how to use it and how to complete it, just like writing an abstract function.

2. Internal interface

The interior of the system can be divided into different subsystems or modules.

How to make function calls and transfer information between subsystems and modules, just write these clearly.
