Ungasebenzisi ikhodi ye-ZIP noma inombolo yezokuphepha yomphakathi
Ulwazi oluxhomeke ezihlwini zokugcina, ukuhlunga, nokuqhathanisa noma ukudala ubuhlobo phakathi kwamarekhodi. Uma uke waba phakathi kolwazi oluthile okwesikhashana, kungenzeka ukuthi uzwe ngezinhlobo ezahlukene zezihluthulelo: izihluthulelo eziyisisekelo, izinkinobho zokubhaliselwa , nezinkino zangaphandle . Uma udala itafula le-database elisha, ucelwa ukuthi ukhethe ukhiye owodwa oyinhloko oyobona irekhodi ngalinye eligcinwe kulelo tafula.
Kungani Isihluthulelo Esiyinhloko Kubalulekile
Ukukhethwa kwesihluthulelo esiyinhloko kungenye yezinqumo ezibaluleke kunazo zonke ozokwenza ekwakhiweni kwedatha entsha . Into ebaluleke kunazo zonke ukuthi kumele uqinisekise ukuthi ukhiye okhethiwe uhlukile. Uma kungenzeka ukuthi amarekhodi amabili-adlule, amanje, noma ikusasa-angaba nenani elifanayo lemfanelo, kuyisinqumo esibi sokhiye oyinhloko.
Esinye isici esibalulekile senkinobho eyinhloko ukusetshenziswa kwalo ngamanye amatafula axhumanisa kuwo kudatha lokuxhumana. Kulesi sici, izenzo ezisemqoka ezisemqoka njenge-target pointer. Ngenxa yalezizinto ezihlukeneyo, ukhiye oyinhloko kufanele ukhona uma irekhodi lwakhiwe, futhi alinakushintsha.
Izinketho ezimbi zamakhidi eziyinhloko
Lokho abanye abantu abangase bacabange ukuthi ukukhetha okusobala okhiye oyinhloko kungaba ukukhetha okungalungile kunalokho. Nazi izibonelo ezimbalwa:
- Amakhodi we-ZIP angenzi izihluthulelo ezinhle ezisemqoka etafuleni lamadolobha. Uma wenza ithebula elilula lokubuka lamadolobha, ikhodi ye-ZIP ibonakala iyinkinobho eyisisekelo enengqondo. Nokho, uma uphenyo olwengeziwe, ungase uqaphele ukuthi idolobha elingaphezu kwelilodwa lihlanganyela ikhodi ye-ZIP. Isibonelo, amadolobha aseNew Jersey aseNeptune, eNeptune City, eTinton Falls, naseWall Township bonke abelana ngekhodi ye-07753.
- Izinombolo Zokuphepha Komphakathi azenzi izihluthulelo ezinhle eziyinhloko ngezizathu eziningi. Abantu abaningi bacabanga ukuthi i-SSN yabo iyimfihlo futhi ayifuni ukuthi ibonakale ngokucacile kubasebenzisi be-database. Abanye abantu abanamazwe we-SSN-angaphandle noma abafuduki abangakaze bathole ikhadi lezokuphepha lezenhlalakahle. I-SSN ingabuye isetshenziswe kabusha ngemva kokufa komuntu. Umuntu angase abe ne-SSN engaphezu kweyodwa ngesikhathi sokuPhathwa kwezokuThuthukiswa koMphakathi kukhipha inombolo entsha kumacala okukhwabanisa noma ukwebiwa kwezisi.
- Amakheli we-imeyli abuye akhethe ukukhetha okusemqoka ukhiye oyinhloko. Nakuba zihlukile, zingashintsha ngokuhamba kwesikhathi. Ngaphezu kwalokho, akuwona wonke umuntu onekheli le-imeyili.
Ukukhetha Isihluthulelo Esiyinhloko Esisebenzayo
Ngakho-ke, yini eyenza ukhiye oyinhloko oyinhloko? Ezimweni eziningi, vula kwisistimu yakho yedatha ukuze uxhaswe.
Umkhuba omuhle ekuklanyweni kwedatha ukusebenzisa ukhiye oyinhloko owenziwe ngaphakathi. Uhlelo lwakho lokuphathwa kwedatha lungenza ngokujwayelekile isihlonzi esiyingqayizivele esingenayo incazelo ngaphandle kwesistimu yedatha. Isibonelo, ungasebenzisa uhlobo lwemininingwane ye-Microsoft Access AutoNumber ukudala insimu ebizwa ngokuthi i-RecordID. Uhlobo lwe-AutoNumber yedatha luyandisa ngokwengeziwe insimu njalo uma udala irekhodi. Ngenkathi inombolo ngokwayo ingenalutho, inikeza indlela enokwethenjelwa yokubhekisela irekhodi ngalinye kumbuzo.
Isihluthulelo esihle esiyinhloko ngokuvamile sifushane, sisebenzisa izinombolo, futhi sigweme izinhlamvu ezikhethekile noma ukuxuba abalingiswa abakhulu nabancane ukuze kube lula ukuhlola okusheshayo kwe-database kanye nokuqhathaniswa.
