With the rapid development of China's economy , People have a growing demand for mobile phones , All kinds of mobile phone software are also widely used , But for mobile phone data information management , Various software for mobile phones are also loved by users , Campus second-hand transactions are widely used by users , For convenience, users can manage the data and information of campus second-hand transactions at any time , A management system based on campus second-hand transaction is developed .
The design of campus second-hand transaction is mainly to consider the functions of the system in detail , After determining the functions to be realized, the interface is designed , In the middle of this, we should also consider how to better combine functions and pages , It is convenient for users to easily and clearly find the information they need , And the later operability of the system platform , Carry out technical development through detailed understanding of information content .
The development and utilization of campus second-hand transactions refer to the existing mature technology , Source code as template , Analyze the combination of function adjustment and the actual needs of campus second-hand transaction management , This paper discusses the use of second-hand transaction management based on campus .
