Database normalization is a key process for designing databases. However, it is one of the most complex topics for students in IT undergraduate programs. This work proposes a new software tool that supports students in the process of normalization. This learning tool allows the students to see step by step how to carry out each normal form up to the 3NF. This tool is based on data analysis of the input table as it is explained in class, and not on analyzing the scheme or initial dependencies defined by business rules. Thus, novel algorithms were developed to process the input table (user‐defined) as well as the tables created during the normalization process. The software was tested in two Database courses, obtaining an important increase in the performance of students who used the tool.
