Chapter1: Introduction
In students’ daily life, students often want to sell some textbooks that they no longer use, want to sell the old one, and get a new one.
Sometimes they also want to buy a second-hand textbooks to use, which is generally more affordable than buying a new one. Buying and selling second-hand textbooks can save students a lot of money. Encouraging
students to use second-hand textbooks is also an environmentally friendly way. This is a very practical economic management method for students who do not yet have a financial source. Because of this demand, there have been second-hand textbooks trading platforms.
In college life, we often see classmates and friends around us selling second-hand textbooks or seeking certain second-hand textbooks. Their common way is to post information in the chat group, but it will soon be covered by other information, or post information on Facebook, but the efficiency is often relatively low because there is no particularly targeted group, the scope is too broad.
University second-hand textbooks trading app, this is an app specifically for student second-hand textbooks trading. It explicitly sets the target group as students and builds a second-hand textbooks trading platform for students. Since everyone is a student, the living conditions are very similar, so the probability that the textbooks you want to buy and sell are in need of each other, greatly improving the transaction efficiency, so that students can take their needs in a timely manner. And all are from a school, so the quality of the transaction has also been greatly improved.
Students can log in to the software with the student account to avoid the problem of fake and low-quality textbooks. Users need to find the type of textbooks, and can also directly search for keywords. Finally, students can determine the place and time of the good transaction, the deals will be done face to face.
This second-hand textbooks school-based trading platform can be extended to every school in the future, bringing convenience to students.
1.1 Project Purpose
