TutNorBD: Assistant for teaching and learning process of relational database normalization up to 3NF from a universal table

Relational database normalization is a formal data organization process that seeks to make the database more flexible by eliminating data redundancy and inconsistencies. Informally, a relational database relationship is often described as "normalized" if it conforms to the third normal form. Most relationships in 3NF are free of insert, update, and delete anomalies. In this work the design of a normalization assistant is presented. The purpose of the presented proposal is to support the teaching and learning process of relational database normalization, making the user take his universal data table to third normal form in an agile and simple way.
