Cím:An examination of the effectiveness of teaching data modelling concepts / Márta Czenky
Dátum:2015

Megjegyzések:The effective teaching of data modelling concepts is very important; it constitutes the fundament of database planning methods and the handling of databases with the help of database management lan-guages, typically SQL. We examined three courses. The students of two courses prepared for the exam by solving tests, while the students of the third course prepared by solving tasks from a printed exercise book. The number of task for the second course was 2.5 times more than the number of task for the first course. The main purpose of our examination was to determine the effectiveness of the teaching of data modelling concepts, and to decide if there is a significant difference between the results of the three courses. According to our examination, with increasing the number of test tasks and with the use of exercise book, the results became significantly better.

Cím:The Efficiency Examination of Teaching of Different Normalization Methods / Czenky Márta
Dátum:2014
ISSN:0975-5985 0975-5705
Megjegyzések: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. In order to improve the efficiency of learning this method 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.
