Ib yam li ntawd, cov duab kos duab sib cuam tshuam yog dab tsi? Peb muaj ob hom kev sib cuam tshuam daim duab hauv UML. Cov kab kos duab ntes lub sijhawm ib ntus ntawm cov lus ntws los ntawm ib yam khoom mus rau lwm tus thiab kev sib koom tes daim duab piav qhia txog lub koom haum ntawm cov khoom hauv ib qho kev koom nrog hauv cov lus ntws.
Ib yam li ntawd, koj tuaj yeem nug, dab tsi yog qhov khoom hauv UML?
Yam khoom . Hauv UML qauv, khoom yog cov qauv qauv uas sawv cev piv txwv ntawm cov chav kawm lossis cov chav kawm. Tus kheej ntawm ib khoom ua rau nws tshwj xeeb. Koj tuaj yeem siv tus cim tshwj xeeb ntawm ib qho khoom kom sib txawv ntawm ntau qhov piv txwv ntawm ib chav kawm yog tias txhua qhov piv txwv muaj tib lub xeev. Txhua khoom yuav tsum muaj lub npe tshwj xeeb.
Dab tsi yog chav kawm thiab khoom hauv UML?
Cov chav kawm : Ib tug qauv tsim khoom thiab siv tus cwj pwm hauv ib qho system. Hauv UML , a chav kawm sawv cev ib khoom los yog ib txheej ntawm khoom uas qhia ib qho qauv thiab tus cwj pwm. Lawv sawv cev los ntawm ib daim duab plaub uas suav nrog cov kab ntawm cov chav kawm lub npe, nws cov cwj pwm, thiab nws cov haujlwm.
