Experiment: write a personnel information management systems. The function of this system are: interactive entry realization of the campus staff and information display.

School, there are four categories of people: college undergraduate students, teachers, graduate students and teaching assistants.
University undergraduates have a fixed number of hours per week. Teachers addition to a fixed number of hours, as well as weekly teaching hours. Graduate addition to a fixed number of hours per week can also do some research freedom. In addition to the extra-curricular teaching assistant students, we need to do some research and teaching.
Basic information of personnel including name, number, gender, ID number, the total number of hours and a fixed number of hours per week. The relationship between the various personnel: people like derived class and the teacher student class, student class derived graduate classes, graduate class and the class teacher TA derived class.
