Aiming at the current teaching status of the Database Principle course, this paper proposes a blended teaching strategy with cases as the core to bridge the course teaching content, projects as the core to optimize the course experimental content, and student as the center. The practice results show that this method can cultivate students' overall thinking of database, improve the quality

of course learning, stimulate students' independent learning ability, and make teaching more in line with the training needs of database talents in the New Engineering.
