Zingaki izinketho ezingena ku-boolean?

Umbuzo Kanambambili Enhliziyweni Eyinkimbinkimbi

Emhlabeni wedatha nokwenza izinqumo, imiqondo embalwa ibonakala iqondile njenge-boolean. Iqanjwe ngesazi sezibalo u-George Boole, i-boolean iwuhlobo lwedatha olunamanani amabili kuphela angaba khona: iqiniso noma amanga, yebo noma cha, kuvuliwe noma kuvaliwe. Ilingana nedijithali yeswishi yokukhanya. Lobu lula buyenza ithuluzi elinamandla lokudala izakhiwo ezicacile, ezinengqondo ngaphakathi kwesofthiwe. Kodwa lapho amabhizinisi eqala ukumodela imisebenzi yawo yomhlaba wangempela ohlelweni olufana ne-Mewayz, kuphakama umbuzo othakazelisayo: Zingaki izinketho ongangena ngokweqiniso embuzweni we-boolean ngaphambi kokuba uphuke? Impendulo inamaphutha amaningi kunalokho ongase ucabange ngakho futhi ihlezi emnyombweni wokwakha i-OS yebhizinisi esebenzayo.

Amandla nobumsulwa be-Boolean

Amandla amakhulu e-boolean ukucaca kwayo okuphelele. Asikho isikhala sokungacaci kahle. Enqubweni yebhizinisi, lokhu kubaluleke kakhulu ezinqumweni ezizenzakalelayo nokudala ukugeleza komsebenzi okuhlanzekile. Ngokwesibonelo, ku-Mewayz, ungase usethe umthetho olula: "Uma i-invoyisi `igunyazwe` (iyiqiniso), yithumele kuklayenti. Uma `ingagunyazwa` (amanga), bese uyibuyisela kumphathi ukuze ibuyekezwe." Leli sango kanambambili liqinisekisa ukuthi imisebenzi iya phambili kuphela uma kuhlangatshezwana nemibandela ethile, okungaxoxiswana ngayo. Iphoqelela ubuqotho benqubo ngaphandle kokukhetha. Ukusebenzisa ama-booleans kulezi zinqumo ezibalulekile, yebo/cha kugcina ingqondo yakho yokusebenza ithambile futhi iqondakala kalula, okuwumgomo oyinhloko wesistimu yokusebenza yebhizinisi ehlelwe kahle.

Lapho Yebo/Cha Olula Akwanele

Inselele ivela lapho umhlaba wangempela wethula izimo ezizwakala sengathi unezinketho ezingaphezu kwezimbili. Cabangela isimo sephrojekthi. Ekuqaleni, ungase ucabange ukuthi i-boolean efana nokuthi `i_iphelele` inganele. Kodwa kuthiwani ngezifunda phakathi kokuqala nokuqedwa? Ingabe iphrojekthi "ayikaqalwa," "iyaqhubeka," "isamisiwe," noma "ilinde ukubuyekezwa"? Ukuphoqelela lezi zifundazwe eziningi endaweni yeqiniso/yamanga kudala "i-boolean trap." Ugcina unamagama enkambu anjengokuthi `a_ayiqaliwe`, `i_iyaqhubeka`, nokuthi `i_imisiwe`, okuba yinhlakanhlaka futhi okungenangqondo. Inani leqiniso elilodwa kuzo zonke izinkambu eziningi lingadala idatha engqubuzanayo. Lokhu kuwuphawu olucacile lokuthi usukhulile kune-boolean futhi udinga uhlobo lwedatha olufaneleka kakhulu.

• Isilingo "Sesifunda Sesithathu": Kwesinye isikhathi, kuba nesifiso sesimo "mhlawumbe" noma "esingasebenzi". Lesi yinkomba yakudala yokuthi i-boolean ukukhetha okungalungile.
• Ubufakazi Besikhathi esizayo: Isinqumo esibonakala singanambambili namuhla singase siguquke. Ukukhetha inkambu yesimo enezinketho eziningi kusukela ekuqaleni kunikeza ukuguquguquka.
• Ukucaciswa Kwedatha: Inkambu yesimo enamalebula acacile (isb., "Okusalungiswa," "Kusalindile," "Kuvunyelwe") ifundeka kakhulu kunenkambu eyimfihlo ethi `iyasebenza` esethwe kumanga.

Ukudizayina I-Modular OS Yakho: Ukukhetha Ithuluzi Elilungile

Ukhiye wokusebenzisa ngempumelelo ama-booleans ngaphakathi kwenkundla efana ne-Mewayz idizayini yamabomu. Kumayelana nokubuza umbuzo olungile wenqubo yakho. I-boolean ifaneleka emibuzweni enambambili ngokwemvelo futhi unomphela. Imvelo ye-modular ye-Mewayz ikuvumela ukuthi uhlanganise izinhlobo zedatha kalula, usebenzisa ngayinye lapho ilingana kahle kakhulu.

"Ubuciko bomklamo wesistimu abukho ekuphoqeleleni iqiniso kumabhokisi kanambambili, kodwa ekwazini ukuthi iziphi izici zebhizinisi lakho ezinambambili ngempela futhi ezidinga indlela ecashile."

Ngokwesibonelo, i-akhawunti yomsebenzisi ingase ibe nenkambu ye-boolean yokuthi `iyasebenza_ukunika amandla noma ukukhubaza ukufinyelela—isimo esinambambili ngempela. Ngaleso sikhathi, i-oda lizosebenzisa inkambu yesimo sezinketho eziningi ukuze ilandelele uhambo lwayo ukusuka kokuthi "Ikalishi" ukuya kokuthi "Okukhokhiwe" kuya kokuthi "Kuthunyelwe." Le ndlela ecatshangelwayo yokumodela idatha iyona eyenza i-OS yebhizinisi ibe namandla. Iqinisekisa ukuthi isistimu yakho ibonisa ngokunembile ubunkimbinkimbi bemisebenzi yakho ngaphandle kokwenza izinto zibe nzima kakhulu.

Isiphetho: Okubili kuyiNkampani, Okuthathu kuwuhlobo Lwedatha Oluhlukile

Ngakho-ke, zingaki izinketho ezingena ku-boolean? Impendulo eqinile, yobuchwepheshe imbili, futhi mibili kuphela. Noma yimuphi umzamo wokucindezela inketho yesithathu uyonakalisa injongo yayo eyisisekelo. Impendulo esebenzayo, egxile ebhizinisini ukuthi kufanele usebenzise kuphela i-boolean ezinqumweni ezizohlala zinemiphumela emibili, kanye nemibili kuphela, ekhethekile. Ngokuhlonipha ubulula be-boolean kanye nokubona imikhawulo yayo, ungakha izinqubo ezihlanzekile, ezinengqondo kakhudlwana, kanye nezinwebekayo ngaphakathi kweplathifomu yakho ye-Mewayz. Umgomo uwukusebenzisa amandla okuthi "yebo" kanye "no-cha" lapho iletha khona umthelela omkhulu, kanye nokusebenzisa ngomusa amanye amathuluzi lapho ingqondo yebhizinisi lakho idinga iphalethi ecebile yezinketho.
