sistema.<\/span><\/h3>\n<p id=\"065e\" class=\"graf graf--p graf-after--h3\">El objetivo de un diagrama de contexto del sistema es centrar la atenci\u00f3n en los factores y eventos externos que deben tenerse en cuenta al desarrollar un conjunto de requisitos y restricciones del sistema.\u00a0Los mapas de contexto del sistema a menudo se usan al principio de un proyecto para determinar el alcance de la investigaci\u00f3n.<\/p>\n<p id=\"4acb\" class=\"graf graf--p graf-after--p\">Un diagrama de contexto del sistema representa todas las entidades externas que pueden interactuar con el sistema.\u00a0Todo el sistema de software parece un solo proceso.\u00a0Dicho diagrama representa un sistema en el centro, sin los detalles de su estructura interna, rodeado por todas las entidades externas y los sistemas interactivos del entorno.<\/p>\n<h4 id=\"787f\" class=\"graf graf--h4 graf-after--p\"><span id=\"What_is_Top-Down_Decomposition\">\u00bfQu\u00e9 es la descomposici\u00f3n de arriba hacia abajo?<\/span><\/h4>\n<p id=\"8d22\" class=\"graf graf--p graf-after--h4\">En el dise\u00f1o de arriba hacia abajo, se dise\u00f1a la visi\u00f3n general del sistema, especificando pero sin detallar ning\u00fan nivel de subsistema.\u00a0Luego, cada subsistema se refina con m\u00e1s detalle, por ejemplo, a veces se divide en muchos niveles de subsistemas diferentes, para descomponer la especificaci\u00f3n completa en elementos b\u00e1sicos.<\/p>\n<p id=\"066a\" class=\"graf graf--p graf-after--p\">El objetivo principal del dise\u00f1o de arriba hacia abajo es descomponer un sistema en partes m\u00e1s peque\u00f1as para comprender sus subsistemas.\u00a0Una vez que se identifican estos elementos b\u00e1sicos, se pueden integrar m\u00e1s f\u00e1cilmente en los m\u00f3dulos de la computadora.\u00a0Una vez que se construyen los m\u00f3dulos, puede unirlos f\u00e1cilmente y construir todo el sistema a partir de estos elementos individuales.<\/p>\n<h3 id=\"f120\"

graf-after--h3\">Un diagrama de contexto brinda una descripci\u00f3n general y es el nivel m\u00e1s alto en un diagrama de flujo de datos, que contiene solo un proceso que representa todo el sistema.\u00a0Debe dividirse en procesos principales que brinden mayor detalle y cada proceso principal puede dividirse a\u00fan m\u00e1s para brindar m\u00e1s detalles.<\/p>\n<ul

proceso \u00fanico en el diagrama de nivel de contexto, que representa todo el sistema, se puede desglosar para incluir los procesos principales del sistema en el siguiente diagrama de nivel, que se denomina diagrama 0.<\/li>\n<\/ul>\n<figure id=\"ae36\" class=\"graf graf--figure graf-after--li\"><img decoding=\"async\" class=\"graf-image\"

diagrama 0 (con un n\u00famero entero) se pueden desglosar a\u00fan m\u00e1s para representar los detalles de las actividades de procesamiento.\u00a0El siguiente ejemplo muestra el siguiente nivel ((Diagrama 1) de la explosi\u00f3n del proceso.<\/p>\n<p id=\"de98\" class=\"graf graf--p graf-after--p\">Tenga en cuenta que:<\/p>\n<p id=\"29f2\" class=\"graf graf--p graf-after--p\">Aunque el siguiente DFD de nivel 1 solo tiene tres procesos, hay bastantes entradas y entradas de los procesos a las entidades externas y eso podr\u00eda terminar siendo unas pocas l\u00edneas cruzadas entre ellas en el diagrama;\u00a0para evitar este problema, podr\u00edamos usar (vista maestra y auxiliar) m\u00faltiples vistas de la misma entidad externa en el DFD.<\/p>\n<figure id=\"43eb\" class=\"graf graf--figure graf-after--p\"><img decoding=\"async\" class=\"graf-image\" src=\"https:\/\/www.cybermedian.com\/es\/wp-content\/uploads\/sites\/8\/2022\/01\/0T29bIDs3UALgHp9a.png\"

2<\/span><\/h3>\n<p id=\"8e78\" class=\"graf graf--p graf-after--h3\">Si un proceso con mucho flujo de datos se vincula entre unas pocas entidades externas, primero podr\u00edamos extraer ese proceso en particular y las entidades externas asociadas en un diagrama separado similar a un diagrama de contexto, antes de refinar el proceso en un nivel separado de DFD;\u00a0y de esta manera puedes asegurar la consistencia entre ellos mucho m\u00e1s f\u00e1cilmente.<\/p>\n<figure id=\"262c\" class=\"graf graf--figure graf-after--p\"><img decoding=\"async\" class=\"graf-image\"
