Preface
With the rapid development of our country's economy, people's demand for mobile phones is increasing, and various mobile phone software are also widely used. However, for data information management on mobile phones, various software for mobile phones are also very popular among users. Campus Comprehensive services are widely used by users. In order to facilitate users to manage the data information of the campus comprehensive service applet at any time, a management system based on the campus comprehensive service applet has been developed.
The design of the campus comprehensive service applet is mainly to consider in detail the functions to be implemented by the system, and then design the interface after determining the functions to be implemented. During this process, we also need to consider how to better combine the functions and pages. , it is convenient for users to easily and clearly find the information they need, and it also provides the later operability of the system platform, and technology development is carried out through a detailed understanding of the information content.
The development of the campus comprehensive service applet uses the existing mature technology reference, uses the source code as a template, analyzes the functional adjustments and combines the actual needs of the campus comprehensive service applet, and discusses the use of the campus comprehensive service applet.
