Wide majors partition is an important task in the management of universities. At present, Most of the partition process is completed by manual diversion, which is heavy loaded, time-consuming, easy to make mistakes, and of low efficiency. To solve those problems, it is proposed to explore the information system of wide major partition process in universities, which discussed the wide major partition admissions algorithms and professional division admission algorithms by designing the voluntary module, the large-scale division module, and the professional division module. It has solved the practical problems of diversion work in universities, and has reduced mistakes, saved labor, and saved time.
