id=\"que_es_una_fila_en_base_de_datos\">\u00bfQu\u00e9 es una fila en base de datos?<\/span><\/h2>\n<p>En las <a href=\"https:\/\/www.techopedia.com\/es\/definicion\/base-datos\">bases de datos<\/a> relacionales, una <strong>fila\u00a0es un registro de datos dentro de una tabla<\/strong>. Cada <span>fila<\/span>, que representa un registro completo de un elemento espec\u00edfico, contiene datos diferentes dentro de la misma estructura.<\/p>\n<p>A veces se hace referencia a las filas<span>\u00a0de datos<\/span> como tuplas. Tambi\u00e9n existen los diccionarios o la listas que, cada una, tiene caracter\u00edsticas diferentes y un caso de uso concreto para almacenar y manipular datos dentro del mundo de la programaci\u00f3n, pero estas se explorar\u00e1n en otro art\u00edculo.<\/p>\n<h2><span id=\"definicion_de_fila_de_base_de_datos\">Definici\u00f3n de fila de base de datos\u00a0<\/span><\/h2>\n<p>Las tablas de bases de datos suelen tener un aspecto similar al de una hoja de c\u00e1lculo. Las tablas relacionales tienen una estructura muy similar pero m\u00e1s compleja, ya que cada columna de la tabla representa una determinada propiedad de la tabla.<\/p>\n<p>Por ejemplo, una tabla llamada CUSTOMER_MASTER podr\u00eda almacenar datos b\u00e1sicos de clientes. Podr\u00eda contener una columna CUSTOMER_LASTNAME, que, como su nombre indica, se utiliza para almacenar el apellido de los clientes.<\/p>\n<p>Esta columna puede tener ciertos par\u00e1metros, como que cada apellido debe tener 30 caracteres o menos y estar compuesto s\u00f3lo por caracteres alfab\u00e9ticos. As\u00ed, cada apellido de cliente a\u00f1adido a la tabla CUSTOMER_MASTER debe cumplir estos par\u00e1metros.<\/p>\n<p>Sin embargo, <strong>cada fila o registro completo de cliente tambi\u00e9n incluye otros elementos<\/strong> (como el nombre, la direcci\u00f3n f\u00edsica, la direcci\u00f3n de correo electr\u00f3nico, la fecha de nacimiento y el sexo, etc.). Al igual que en una hoja de c\u00e1lculo, cada elemento est\u00e1 ordenado en las columnas correspondientes. As\u00ed, cada fila o registro de cliente es una l\u00ednea horizontal de datos que contiene una colecci\u00f3n de elementos.<\/p>\n<p>Aunque el cliente final que interact\u00faa con un programa o app, poco puede percibir las <span>filas de datos, es cierto que el programador que estuvo desarrollado dicho programa, pudo haber hecho uso de este elemento para brindar una mejor experiencia de usuario.\u00a0<\/span><\/p>\n<h2><span id=\"importancia_de_las_filas_en_las_bases_de_datos\">Importancia de las filas en las bases de datos\u00a0<\/span><\/h2>\n<p><span style=\"font-weight: 400\">Aparte de su funcionalidad a la hora de almacenar y organizar la informaci\u00f3n, las filas en las bases de datos tienen mucha importancia por varias razones que te explicamos a continuaci\u00f3n:<\/span><\/p>\n<p><span style=\"font-weight: 400\"><div class=\"su-tabs su-tabs-style-default su-tabs-mobile-stack su-tabs-vertical\" data-active=\"1\" data-scroll-offset=\"0\" data-anchor-in-url=\"no\"><div class=\"su-tabs-nav\"><span class=\"\" data-url=\"\" data-target=\"blank\" tabindex=\"0\" role=\"button\">Facilitan el almacenamiento de datos <\/span><span class=\"\" data-url=\"\" data-target=\"blank\" tabindex=\"0\" role=\"button\">Mantienen la integridad en la informaci\u00f3n<\/span><span class=\"\" data-url=\"\" data-target=\"blank\" tabindex=\"0\" role=\"button\">Facilitan las consultas y las b\u00fasquedas <\/span><span class=\"\" data-url=\"\" data-target=\"blank\" tabindex=\"0\" role=\"button\">An\u00e1lisis de datos<\/span><span class=\"\" data-url=\"\" data-target=\"blank\" tabindex=\"0\" role=\"button\">Crean relaciones entre tablas<\/span><\/div><div class=\"su-tabs-panes\"><div class=\"su-tabs-pane su-u-clearfix su-u-trim\" data-title=\"Facilitan el almacenamiento de datos \"><\/span><\/p>\n<p><b>Cada fila representa un \u00fanico conjunto de datos<\/b><span style=\"font-weight: 400\">, por lo que almacenan toda la informaci\u00f3n relevante sobre una entidad espec\u00edfica, como un cliente, producto o transacci\u00f3n, adem\u00e1s de que ordenan por jerarqu\u00eda cada uno de esos datos.<\/span><\/p>\n<p><span style=\"font-weight: 400\"><\/div>\n<div class=\"su-tabs-pane su-u-clearfix su-u-trim\" data-title=\"Mantienen la integridad en la informaci\u00f3n\"><\/span><\/p>\n<p><span style=\"font-weight: 400\">Por otra parte, es un elemento que <\/span><b>permite la organizaci\u00f3n estructurada y coherente de datos.
