Diagrama de fluxo de dados (DFD)<\/h1>\n

A Dados<\/a> O Diagrama de Fluxo, vulgarmente conhecido como DFD, \u00e9 uma representa\u00e7\u00e3o gr\u00e1fica do fluxo de dados atrav\u00e9s de um sistema. \u00c9 uma ferramenta poderosa para analisar, projetar e documentar sistemas complexos. O DFD fornece uma representa\u00e7\u00e3o visual de como os dados se movem atrav\u00e9s de um sistema, desde a entrada at\u00e9 a sa\u00edda. Mostra as fontes de dados, os destinos dos dados, o armazenamento de dados e os processos que transformam os dados.<\/p>\n

O DFD \u00e9 uma ferramenta essencial para programadores de software<\/a>A an\u00e1lise de dados \u00e9 efectuada por analistas de sistemas, analistas de sistemas e analistas de neg\u00f3cios. Ajuda-os a compreender os requisitos do sistema, o fluxo de dados e as rela\u00e7\u00f5es entre os diferentes componentes do sistema. O DFD \u00e9 frequentemente utilizado nas fases iniciais do projeto. desenvolvimento de software<\/a> ciclo de vida para identificar os requisitos e conceber a arquitetura do sistema.<\/p>\n

O DFD \u00e9 composto por quatro componentes principais: fontes de dados, destinos de dados, armazenamento de dados e processos. As fontes de dados s\u00e3o os inputs do sistema, tais como utilizadores, sensores ou outros sistemas. Os destinos dos dados s\u00e3o os outputs do sistema, como relat\u00f3rios, ecr\u00e3s ou outros sistemas. O armazenamento de dados \u00e9 o local onde os dados s\u00e3o armazenados, como bases de dados, ficheiros ou mem\u00f3ria. Os processos s\u00e3o as ac\u00e7\u00f5es que transformam os dados, tais como c\u00e1lculos, valida\u00e7\u00f5es ou transforma\u00e7\u00f5es.<\/p>\n

O DFD utiliza s\u00edmbolos para representar cada componente do sistema. Os s\u00edmbolos incluem c\u00edrculos, rect\u00e2ngulos e setas. Os c\u00edrculos representam as fontes, os destinos e o armazenamento de dados. Os ret\u00e2ngulos representam os processos. As setas representam o fluxo de dados entre os componentes.<\/p>\n

O DFD \u00e9 uma ferramenta poderosa para analisar e documentar sistemas complexos. Ajuda os programadores a compreender os requisitos do sistema, a conceber a arquitetura do sistema e a comunicar a conce\u00e7\u00e3o do sistema a outras partes interessadas. O DFD tamb\u00e9m \u00e9 \u00fatil para identificar potenciais problemas e estrangulamentos no sistema, e para melhorar o desempenho e a efici\u00eancia do sistema.<\/p>\n
