ohjelmistokehitys<\/a> elinkaaren aikana vaatimusten tunnistamiseksi ja j\u00e4rjestelm\u00e4arkkitehtuurin suunnittelemiseksi.<\/p>\nDFD koostuu nelj\u00e4st\u00e4 p\u00e4\u00e4komponentista: tietol\u00e4hteist\u00e4, datakohteista, datan tallennuksesta ja prosesseista. Tietol\u00e4hteet ovat j\u00e4rjestelm\u00e4n sy\u00f6tteit\u00e4, kuten k\u00e4ytt\u00e4j\u00e4t, anturit tai muut j\u00e4rjestelm\u00e4t. Tietokohteet ovat j\u00e4rjestelm\u00e4n tuotoksia, kuten raportit, n\u00e4yt\u00f6t tai muut j\u00e4rjestelm\u00e4t. Tietojen varastointi on paikka, johon tiedot tallennetaan, kuten tietokannat, tiedostot tai muisti. Prosessit ovat toimia, jotka muuttavat tietoja, kuten laskutoimitukset, validoinnit tai muunnokset.<\/p>\n
DFD:ss\u00e4 k\u00e4ytet\u00e4\u00e4n symboleja kuvaamaan j\u00e4rjestelm\u00e4n kutakin komponenttia. Symboleihin kuuluvat ympyr\u00e4t, suorakulmiot ja nuolet. Ympyr\u00e4t edustavat tietol\u00e4hteit\u00e4, -kohteita ja -varastoja. Suorakulmiot edustavat prosesseja. Nuolet kuvaavat komponenttien v\u00e4list\u00e4 tiedonkulkua.<\/p>\n
DFD on tehokas ty\u00f6kalu monimutkaisten j\u00e4rjestelmien analysointiin ja dokumentointiin. Se auttaa kehitt\u00e4ji\u00e4 ymm\u00e4rt\u00e4m\u00e4\u00e4n j\u00e4rjestelm\u00e4n vaatimuksia, suunnittelemaan j\u00e4rjestelm\u00e4n arkkitehtuurin ja v\u00e4litt\u00e4m\u00e4\u00e4n j\u00e4rjestelm\u00e4n suunnittelun muille sidosryhmille. DFD on hy\u00f6dyllinen my\u00f6s j\u00e4rjestelm\u00e4n mahdollisten ongelmien ja pullonkaulojen tunnistamisessa sek\u00e4 j\u00e4rjestelm\u00e4n suorituskyvyn ja tehokkuuden parantamisessa.<\/p>\n
