Cím:	Normalization Based on Dependency Diagram / Czenky Márta
Dátum:	2010
ISSN:	1589-7389
Megjegyzések:	Normalization is an important database planning method, although the understanding and appli-cation of this method brings up the most problem during data modelling. That is why we were looking for alternative normalization methods, from which the normalization with dependency diagram proved to be the most efficient. This was confirmed by the statistical estimation of the carried out survey.

Cím:	Concept systematization with concept maps in data modelling / Márta Czenky, János Kormos
Dátum:	2014
ISSN:	1589-7389
Megjegyzések:	An important goal of concept learning is that students can allocate conceptsin the hierarchical system of concepts. In the data modelling course, first, we supportedconcept systematization with worksheets in which the students had to fill in the blankhierarchical figures of classification of the concepts or blank Venn diagrams describingthe relationships between concepts. The hierarchical systems, however, are somewhatrestricted to the description of connections. The filling in Venn diagrams did not deliverthe expected result, so our attention turned to concept maps. In this paper we introducethe concept maps we drew. Then we evaluate the results of concept mapping surveyconducted among students. The survey was done in three courses. We compare theresults of our survey with the result of an earlier concept systematising survey.
