Las Bases de datos son colecciones de informaci n (datos) que se relacionan para crear un sentido y dar m s eficiencia a una encuesta, un estudio organizado o la estructura de datos de una empresa. Son de vital importancia para las empresas, y en las ltimas d cadas se han convertido en la parte principal de los sistemas de informaci n. Normalmente los datos permanecen all durante varios a os sin necesidad de cambiar su estructura.Las bases de datos suelen ser gestionadas por sistemas de gesti n de bases de datos (SGBD), que surgieron en los a os 70. Antes de estos, las aplicaciones utilizadas en los archivos del sistema operativo para almacenar sus sistemas de informaci n. En los a os 80 la tecnolog a de SGBD relacional lleg a dominar el mercado, y en la actualidad se utiliza casi exclusivamente. Otro tipo de bases de datos destacadas son los SGBD orientados a objetos, donde su estructura o aplicaciones que lo utilizan est n en constante cambio.
