Abstract


This paper presents a web application to support the teaching-learning process of undergraduate database courses, which allows students to practice their knowledge on data modeling using Entity-Relationship (E-R) diagrams. The web application is oriented to teachers and students: teachers prepare examples and exercises, which can have associated E-R diagrams; on the other hand, students are able to design E-R diagrams, which they can review at any time, they also have the option of viewing and solve some of the exercises designed by the teacher. The development of the web application is explained; a comparison of similar existing E-R diagram systems is presented; and the operation of the web application is shown through the creation of an E-R diagram. The results of an instrument applied to students for the evaluation of the web application are provided.
