Experience of a didactic tool as a support in the learning of relational algebra

Abstract

In this paper we present some preliminary results and conclusions about the experience of using a tool designed and developed as a support for the teaching of relational algebra. Through the tool you can design queries in relational algebra, check their operation and performance, step by step, visually. The experiences were applied to an introductory course of databases in the Engineering in Software Development, of the Autonomous University of Baja California Sur (UABCS). Some theoretical references are presented that support the proposal and make a description of the application context. Finally, the results of the use and conclusions obtained are presented.
