Cov khoom ntws piav txog cov ntws ntawm khoom thiab cov ntaub ntawv hauv kev ua si . Ntug tuaj yeem sau nrog lub npe (ze rau ntawm xub): Cov khoom ntws hauv ib daim duab kos duab qhia txoj hauv kev ntawm ib lossis ntau lub lag luam khoom nruab nrab ntawm ntau yam kev ua si.
Ntawm no, dab tsi node nyob rau hauv daim duab kos duab?
Ib khoom node yog abstract kev ua haujlwm node uas yog siv los txhais khoom flows ib kev ua si . Object nodes suav nrog tus pin, central buffer, parameter, expansion nodes . Nws yog qhov txawv me ntsis txawm tias khoom node yog abstract kev ua haujlwm node , nws yog siv ncaj qha rau hauv khoom ntws siv nws tus kheej sau ntawv (saib hauv qab).
Tsis tas li ntawd, dab tsi yog qhov kev nqis tes ua hauv daim duab kos duab? Kev ua . UML, ib kev ua sawv cev rau ib tug discrete unit ntawm functionality nyob rau hauv ib kev ua si . Kev ua muaj kev nkag thiab tawm kev ua si cov npoo uas qhia txog kev khiav ntawm kev tswj thiab cov ntaub ntawv mus rau thiab los ntawm lwm yam kev ua si nodes. Cov kev ua hauv ib kev ua si pib thaum tag nrho cov ntsiab lus nkag tau ua tiav.
Ua raws li qhov no, dab tsi yog cov khoom hauv daim duab kos duab?
Cov duab kos duab suav nrog swimlanes, branching, parallel flow, control nodes, expansion nodes, thiab object nodes.
Daim Ntawv Qhia Ua Haujlwm puas muaj kev hloov pauv?

Dab tsi yog cov khoom node hauv daim duab kos duab?
Cov khoom node yog ib qho kev ua haujlwm tsis txaus ntseeg uas yog siv los txhais cov khoom ntws hauv ib qho kev ua si. Cov khoom nodes muaj xws li tus pin, central buffer, parameter, expansion nodes. Nws yog qhov txawv me ntsis tias txawm hais tias cov khoom node yog qhov kev ua haujlwm tsis txaus ntseeg, nws tau siv ncaj qha rau hauv cov khoom ntws siv nws tus kheej cov cim (saib hauv qab)
Dab tsi yog kev tiv thaiv hauv daim duab kos duab?
Tus neeg saib xyuas yog ib qho xwm txheej uas yuav tsum muaj tseeb txhawm rau hla kev hloov pauv. Txhua qhov kev hloov pauv tawm qhov kev txiav txim siab yuav tsum muaj tus neeg saib xyuas. Cov Guards yuav tsum tsis txhob sib tshooj
Dab tsi yog qhov txawv ntawm lub xeev daim duab kos duab thiab daim duab ua haujlwm?
Lub xeev daim duab qauv yog siv los qhia qhov sib lawv liag ntawm lub xeev uas ib yam khoom mus dhau, qhov ua rau kev hloov ntawm ib lub xeev mus rau lwm qhov thiab qhov kev txiav txim uas tshwm sim los ntawm lub xeev hloov. Daim duab ua haujlwm yog ntws ntawm kev ua haujlwm yam tsis muaj qhov tshwm sim (kev tshwm sim) mechanism, lub xeev tshuab yog suav nrog lub xeev triggered
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
