Abstract: At present, the society has entered the era of big data, and vocational colleges have set up big data technology specialty. As a new engineering specialty, it is more difficult to cultivate. Therefore, how to accurately position the big data specialty and how to finely educate people has become an important topic. Based on the needs of enterprises, we collect big data of enterprise recruitment, build a big data talent analysis platform, focus on big data processing, data visualization and other posts, and cultivate high skilled talents. Project practice runs through the whole process of teacher training and student training, and then builds a series of teaching, feedback teaching. In classroom, teachers and students build a "classroom teaching community", implement group learning, and achieve certain results.
