Query: The Efficiency Examination of Teaching of Different Normalization
  Methods   Normalization is an important database design method, in the course of the
teaching of data modeling the understanding and applying of this method cause
problems for students the most. For improving the efficiency of learning
normalization we looked for alternative normalization methods and introduced
them into education. We made a survey among engineer students how efficient
could they execute the normalization with different methods. We executed
statistical and data mining examinations to decide whether any of the methods
resulted significantly better solutions.
