First, the technical content. The first concern of graduation defense of computer major is whether the technical content involved in graduation design can meet the training requirements. Undergraduate students should have preliminary scientific research ability, and graduate students should have certain innovation ability. Take undergraduates as an example, if the topic involves the invoicing management system.

Second, the rationality of the technical scheme. Another problem that graduation defense teachers pay more attention to is the rationality of technical scheme. There are three common key points. First, how to choose the technical scheme; Second, whether there is room for expansion; The third is whether it can be applied. Taking the invoicing system as an example, there are many technical options.

Third, technical details. Technical details are often concerned by teachers, in order to test students' mastery of technology and practical ability. Technical details usually have three aspects: one is to describe the realization process of a function; The second is a question about database operation; The third is to ask questions about the algorithm.

Fourth, on the one hand, we need to be fully prepared, on the other hand, we need to be flexible. When the teacher's question is not fully understood, we can give our own plan by solving the problem. There are many different schemes for the same problem. It must be remembered that any scheme can explain the problem.

The defense process:

1. Students must submit their graduation thesis in triplicate, together with the outline and draft, half a month before the thesis defense meeting, which has been approved and signed by the tutor. The main defense teacher of the defense Committee will work out the questions to be asked on the basis of carefully studying the graduation thesis, and then hold a defense meeting.

2. At the defense meeting, let students spend about 15 minutes outlining the topic and the reasons for choosing the topic, and introduce the main arguments, arguments and writing experience of the paper in detail.

3. The main defense teacher asks questions. The main defense teacher usually asks three questions. After the teacher asks questions, some schools stipulate that students can preview 15-20 minutes independently, and then come back to answer on the spot, while the Correspondence College of the Central Party School stipulates that students are required to answer on the spot immediately after the main defense teacher asks questions.

The students answered all the questions one by one and left. According to the quality of the paper and the defense situation, the defense Committee collectively decides whether to pass or not, and formulates achievements and opinions.
