1. Front desk:

The front desk refers to the interface and functions that App users directly contact and use. Including user interface, interaction design, visual effect, user operation, etc. Foreground development mainly involves user interface design and front-end programming, aiming at providing good user experience and functional realization.

Foreground development usually involves the following tasks:

-User interface design: design attractive, intuitive and easy-to-use interfaces, including icons, buttons, menus, etc.

-Front-end programming: using front-end technologies such as HTML, CSS and JavaScript. Interface interaction, data display and user operation response are realized.

-User experience optimization: pay attention to user operation process, interface feedback, animation effect, etc. So as to improve user satisfaction and ease of use.

2. Backstage:

The background refers to the server-side system and data processing part behind the App. It is mainly responsible for data storage, processing, logical operation and interaction with the foreground. Background development usually involves database design, server-side programming and API interface development.

The main tasks of background development include:

-Database design: design an appropriate database structure to store and manage App data, such as user information, application settings, content, etc.

-Server-side programming: using back-end programming languages such as Python, Java and PHP. Write server-side logic and data processing code.

-API interface development: design and implement an interface for data exchange between foreground and background, allowing data transmission and communication between foreground and background.

The reasonable design and cooperative work of the foreground and background is an important factor to realize a complete, efficient and stable mobile App.
