UML-case idayagramu

I sekulingisa wasebenzisa izinhlobo ezinhlanu amashadi, UML-case umdwebo yindlela simulating izici okuguquguqukayo ohlelweni ukuthi akhombe ukuziphatha izinhlelo ekilasini futhi subsystems ingafeza lukhulu. Esimweni ngasinye kulezi imidvwebo eziningi abadlali, sebenzisa izimo, kanti nobuhlobo phakathi kwazo.

UML-case umdwebo kabanzi emikhakheni ehlukahlukene, ikakhulukazi ezindaweni lapho kudingeka khona kohlelo ngokoMthetho okuhlukile ukusetshenziswa noma izibonelo. Ezimweni eziningi, kucatshangwa lapha akhombe umongo uhlelo nekilasi noma subsystem noma akhombe izimfuneko ezisebenza ukuziphatha ezikhethiwe.

Lokubaluleke kakhulu ukusetshenziswa icala idayagramu for ecacisa, ukubona ngeso kanye nezincwadi uhlelo ukuziphatha. Ukusebenzisa ke, onjiniyela kulula ukuqonda uhlelo, subsystem, noma amakilasi, kanye ukubheka izinzuzo usebenzisa izingxenye sangaphandle esimweni esithile. Okunjalo UML-umdwebo kubaluleke ngokukhethekile ngokuhlola izinhlelo elisebenzisekayo design ngqo, kanye ukuze uqonde kangcono ukuthi isakhiwo sabo sangaphakathi, ikakhulukazi kwezobunjiniyela reverse.

Ukwakheka sandulela - ke iyithuluzi omkhulu ukubheka elinye ithuba simo main, okuyinto kuholela empumelelweni. Kuzo zonke isinyathelo, zibuze umbuzo ngokuphindaphindiwe: "? Yini okunye kwenzeke" Futhi ngokukhethekile, "Yini engase yonakale," lapho engcono kusukela ekuqaleni ukuthola zonke izimo izandiso zingenzeka. Lokhu kuzosiza kugwenywe ukudideka esikhathini esizayo, lapho besebenza emasimini ngemiphumela.

Zonke izimo ukuxazulula inkinga, okuyinto engavumelekile itholakala kuphela, kungcono ukufunda kusukela ekuqaleni. Le ndlela kuyosisiza ukuba sigweme ukubanjwa abasuke bengene shí quagmire lapho abasebenza ngemiphumela. Ngakho-ke, uma kungenzeka, cabanga ngangokunokwenzeka izimo, futhi lokhu kuyoyithinta zinciphisa amaphutha esikhathini esizayo.

Inketho engcono ngokusebenzisana graphic umdwebo izibonelo ithebula elibonisa elikuqukethe. Kuthi afana umdwebo umongo, okuyinto esetshenziswa izindlela kwesakhiwo. Phela, etafuleni elibonisa imingcele kohlelo, kanye tangency yayo nezwe elingaphandle.

Ishadi wabonisa ngokucacile izibonelo abalingisi, izimo ukusetshenziswa, kanye ubuhlobo phakathi kwabo:

- ukukhishwa abadlali ka isibonelo;

- izibonelo ezihilela nezinye izibonelo.

Mayelana okuqukethwe esidlule ukumodeliswa ka UML alisho lutho, futhi indlela lokunikeza shadi libonisa konke. Nokho, ungenza ngaphandle ishadi. Ochwepheshe batusa ukuthuthukiswa precedent ayenzi umzamo kakhulu ukwakha ishadi. Kungaba ngcono uma gxila umbhalo okuqukethwe.

UML zisebenzisa icala umdwebo, ngaphezu zihlanganisa ubudlelwano, has ezinye izinhlobo, isibonelo ukunweba. Kwaba ochwepheshe yakhe Sisikisela ukugwema. Isizathu itholakala lokuthi ngokuvamile lonke ukuthuthukiswa ithimba isikhathi esiningi inikezwe kuhlolwe ubudlelwano ezihlukahlukene phakathi Ukusebenzisa. Lokhu kuwukuchitha umzamo. Ngemva ekubhekaneni incazelo umbhalo kufaniswe zibelula, kulapha lapho ukubaluleka ubuchwepheshe kufihlwe kweqiniso.
