ResumenEste artículo propone extender el lenguaje SQL al crear nuevos tipos de datos con sus respectivos operadores, que permitan crear y manipular objetos simbólicos directamente sobre las bases de datos. La funcionalidad de la extensión propuesta se valida realizando transformaciones de datos relacionales clásicos a objetos simbólicos en bases de datos de gran volumen. Para los usuarios no familiarizados con el lenguaje SQL, se construye una interfaz de usuario final, que facilita y guía el proceso de transformación simbólica.Palabras claves: Base datos; extensión; objeto-relacional; objeto simbólico; SQL. AbstractThis article proposes extend the SQL language with new data types and operators for create and manipulate symbolic objects directly in the database. The functionality of the proposed extension is validated by performing transformations of classical symbolic objects to relational data bases of large data. For users not familiar with the SQL language, a final user interface is built to facilitate and guide the process of symbolic transformation.
