Resumen
This paper aims to present the development of LearnAlgTool system whose function is to assist in learning the basic operations of relational algebra. The relational algebra is a procedural query language, consisting of a set of operations having as input one or two relations and producing, as a result, a new relation. The relational algebra provides a formal foundation for operations in the relational model, and is used as a basis to implement and optimize queries in systems of managers of relational database. The difficulty in finding tools that interpret queries using relational algebra hinders student learning in undergraduate computing course that have database disciplines. Two tools found were analyzed, and the positive and negative aspects of each software helped to make decisions about what could be done. This paper documents the construction of a system that simulates queries using the syntax of the relational algebra, to assist in learning basic operations. The system was developed on the bases of supplying the needs of the existing software.
