          Abstract

          Las bases de datos espacio-temporales permiten representar objetos y fenómenos del mundo real que cambian de posición o forma a medida que transcurre el tiempo. En la última década se han propuesto diversos lenguajes de consulta para dicho tipo de bases de datos. En este artículo se comparan dos de estos lenguajes: SQL ST y el de Güting. La comparación se realiza por medio de criterios que se han aplicado a lenguajes de programación, pero que se han adaptado para evaluar lenguajes de consulta de bases de datos. Los resultados permiten concluir que el alto grado de expresividad evidenciado por ambos lenguajes puede afectar otros criterios, como la legibilidad y la simplicidad, especialmente en el caso del lenguaje de Güting.

          Translated abstract

          Spatio-temporal databases allow us to represent objects and phenomena from the real world which change position or shape as time elapses. Several query languages have been proposed during the last decade to deal with this type of database. Two of these languages have been compared in this paper: SQL ST and Güting’s language. The comparison was based on criteria which have been applied to programming languages; however, they were adapted here to evaluate database query languages. The results led to concluding that both languages high degree of expressiveness may affect other criteria such as readability and simplicity, especially in the case of Güting’s language.
