At Szent István University we teach database management in the framework of several subjects. For preparation for the data modeling exam students of one of these courses prepared with help the electronic tests of Moodle e-learning education system, while the attendees of the other course used printed data modeling exercise book, we wrote him based on the inspiration of students’ demand. With examinations based upon statistical methods we looked for an answer to see whether one of the preparation methods yield significantly better results. We analyzed whether there is any remarkable difference between the advantages and disadvantages of the two ways of preparation. We made a survey among students to see which of the preparation methods is favored by them. Based on the outcome of the analysis we are going to decide which one of preparation methods will be recommended by us as teachers.
