Sicolisa incazelo yemisebenzi yesistimu sisebenzisa umdwebo wokulandelana (ukuqhubeka "kwamaprotheni").
Kulesi sihloko, sizocubungula ukuthi ungacwengisa kanjani (ucacise) incazelo yomsebenzi ozenzakalelayo usebenzisa i-UML Sequence Diagram - idayagramu yokulandelana.
Kulesi sibonelo, ngisebenzisa imvelo ye-Enterprise Architect evela enkampanini yase-Australia. [1].
Ukuze uthole imininingwane ephelele ye-UML, bheka [2].
Okokuqala, ngizochaza ukuthi sizochaza ini.
Π silinganise izinqubo zendawo yesifundo βenhleβ β umugqa omayelana nengwejeje ophuma kweka-A.S. Pushkin ethi The Tale of Tsar Saltan. Futhi siqale ngomdwebo womsebenzi. Bese ungena sakha imodeli esebenzayo sisebenzisa umdwebo we-Use-case diagram, Umfanekiso 1 ubonisa ucezu.
Umfanekiso 1 Ubudlelwano phakathi kwemfuneko kanye nesici
Manje sifuna ukucacisa ulwazi mayelana nokwenziwa kwalo msebenzi ozenzakalelayo:
- yiziphi izakhi zokusebenzelana umsebenzisi wethu azosebenzisana nazo;
- yiziphi izingxenye zokulawula esizidingayo;
- sizogcinani;
- yimiphi imilayezo umsebenzisi kanye nezingxenye zesistimu ezizoshintshana ngazo ukwenza umsebenzi.
Izakhi eziyinhloko zomdwebo wokulandelana yizinto ezisebenzisanayo ezinemibono ehlukene kanye nokuxhumana phakathi kwazo - izinto ezisebenzisanayo zishintshana ngolwazi oluthile (Umfanekiso 2).
Umfanekiso 2. Izakhi eziyinhloko zomdwebo wokulandelana
Izinto zihlelwa ngokulandelana okuvundlile, imilayezo idluliswa phakathi kwazo. I-eksisi yesikhathi iqondiswe ukusuka phezulu kuye phansi.
Isici somlingisi singasetshenziswa ukumela umsebenzisi oqala uchungechunge lwemicimbi.
Into ngayinye inomugqa onachashazi obizwa ngokuthi "umugqa wempilo" lapho leyo elementi ikhona futhi ibamba iqhaza ekuhlanganyeleni. Ukugxila kokulawula kuboniswa unxande emugqeni wempilo wento.
Imilayezo eshintshaniswa phakathi kwezinto ingaba yezinhlobo ezimbalwa, imilayezo ingase futhi yenziwe ngendlela oyifisayo ukuze ibonise ukusebenza nezakhiwo zomthombo nezinto eziqondiwe.
Izakhi ze-stereotypical ezifana ne-Boundary, Control, kanye nebhizinisi zingasetshenziswa ukwenza imodeli yesixhumi esibonakalayo somsebenzisi (i-GUI), izilawuli, nezici zesizindalwazi, ngokulandelana.
Ukugeleza komlayezo ophindaphindayo kungaqokwa njengesiqephu esinohlobo lwe-"loop".
Ngakho, sihlela ukucacisa incazelo yomsebenzi "Engeza ulwazi mayelana nenati elisha esitatimendeni".
Ake sivumelane ngalokhu okulandelayo okujwayelekile kanye nokuqagela.
- Amantongomane, ama-kernels namagobolondo angamanani abonakalayo ezinhlobo ezifanele (Umfanekiso 3).
Umfanekiso 3. Ukulungiswa Kwedayagramu Yekilasi - Umsebenzisi wethu uzofaka imininingwane mayelana nanoma imaphi amanani ezinto ezibonakalayo esitatimendeni.
- Ake sicacise igama leshidi - "Isitatimende sokubala samanani wezinto ezibonakalayo."
- Ake sicabange ukuthi umsebenzisi wethu, esebenza ne-GUI "Ishidi lokubala lamanani wezinto ezibonakalayo", angangeza inani elisha lezezimali nge-GUI "Ikhadi lokubala lamanani wezinto ezibonakalayo".
- Kuye ngohlobo lwevelu, ukwakheka kwedatha kanye ne-GUI kuyashintsha.
- Lapho ugcwalisa izinkambu zekhadi lokubalwa kwenani lempahla, ukufaneleka kwedatha efakiwe iyahlolwa.
Umdwebo owakhiwe unalokhu kucabangela uboniswa kuMfanekiso 4.
Umfanekiso 4. Ukucaciswa kwencazelo yomsebenzi "Engeza ulwazi mayelana nenati elisha esitatimendeni"
