Ezi mpawu maziodolwe ngokwahlukeneyo.
Akukho namnye kuthi ocinga ngezinto ezimbi de kwenzeke into embi. Kwaye ke ukuzisola kuyaqala kunye nentetho malunga nento ebesinokuyenza ukuyithintela. Sicebisa ukuba singalindi de kubethe iindudumo. Masingene ngqo kwisihloko esibaluleke kakhulu ' sogcino lolwazi '. Ukukhusela ulwazi yinto ekufuneka yenziwe ngoku ukuze kungabikho emva kwexesha. ' Universal Accounting System ' inokuqinisekisa ukhuseleko kunye nokhuseleko lolwazi. Kodwa kule nto kufuneka uthathe amanyathelo athile.
Ukugcinwa kwedatha kuphunyezwa ngokukopa isiseko sedatha. I-backup yedatabase yi-backup yeprogram esebenzisa i-database. Ngokuqhelekileyo, i-database isetyenziswa yiyo nayiphi na inkqubo esebenza ngandlela-thile ngolwazi. Ukusebenzisa uvimba weenkcukacha kuthetha ukusebenzisana nenye inkqubo ebizwa ngokuba ' yinkqubo yolawulo lwesiseko sedata '. Ishunqulelwe njenge ' DBMS '. Kwaye ingxaki kukuba awukwazi ukwenza ikopi ngokukopa iifayile zeprogram. Ugcino logcino lwedatha kufuneka lwenziwe kusetyenziswa iminxeba ekhethekileyo yokusebenza yenkqubo yolawulo lwesiseko sedata .
Inkqubo iqhuba kumncedisi. Umncedisi yi hardware . Njengayo nayiphi na i-hardware, umncedisi akahlali ngonaphakade. Nasiphi na isixhobo sinomkhwa ombi wokuqhekeka ngexesha elingalunganga. Ewe, oku kuyahlekisa. Akukho xesha lilungileyo lokuqhawula. Akukho namnye kuthi olinda into ayisebenzisayo ukuba yophule.
Kuba buhlungu ngakumbi xa uvimba wedatha uqhekeka. Oku kunqabile kakhulu, kodwa kuyenzeka. Ikakhulu ngenxa yokumka kombane ngesiquphe. Ngokomzekelo, enye idatha ifakwe kwi-database, kwaye ngelo xesha kanye amandla acinywa ngokukhawuleza. Kwaye awunawo unikezelo lwamandla olungaphazamisekiyo. Kuya kwenzeka ntoni kule meko? Kule meko, ifayile yedatabase iya kuba nexesha lokuzalisa ngokuyinxenye kuphela ngalo lonke ulwazi ozame ukulongeza. Ushicilelo aluyi kugqitywa ngokufanelekileyo. Ifayile iya kwaphulwa.
Omnye umzekelo. Ulibele ukufaka i-antivirus. Intsholongwane ibanjiwe kwi-Intanethi ethatha indawo, ifihla, okanye yonakalise iifayile zeprogram. Kuko konke! Emva koko, awuyi kuba nakho ukusebenzisa inkqubo yosulelo.
Kwenzeka ukuba nezenzo zabasebenzisi zingonakalisa isoftware. Zimbini iindidi zezenzo ezikhohlakeleyo: engenziwanga ngabom. Oko kukuthi, mhlawumbi umsebenzisi wekhompyuter ongenamava angenza ngokungazi into eya konakalisa inkqubo. Okanye, ngokuchaseneyo, umsebenzisi onamava ngokukodwa unokulimaza umbutho, umzekelo, xa kukho ukugxothwa phambi kokungqubuzana kunye nentloko yeshishini.
Kwimeko yefayile ephunyezwayo yenkqubo, enolwandiso ' EXE ', yonke into ilula. Kuya kukwanela ukuba uqale ukhuphele le fayile kube kanye kwindawo yokugcina yangaphandle, ukuze kamva inkqubo inokubuyiselwa kuyo xa kukho ukungaphumeleli okwahlukeneyo.
Kodwa oku akunjalo nge-database. Ayinakukhutshelwa kanye ekuqaleni komsebenzi kunye neprogram. Ngenxa yokuba ifayile yedatha itshintsha yonke imihla. Yonke imihla uzisa abathengi abatsha kunye neeodolo ezintsha.
Kwakhona, ifayile yedatha ayikwazi ukukopishwa njengefayile elula. Ngenxa yokuba ngexesha lokukopa i-database ingasetyenziswa. Kule meko, xa ukopisha, unokugqiba ngekopi ephukileyo, ongayi kukwazi ukuyisebenzisa xa kukho ukungaphumeleli okuhlukeneyo. Ngoko ke, ikopi evela kwisiseko sedatha yenziwa ngokwahlukileyo. Wonke umntu ufuna ikopi efanelekileyo yesiseko sedatha.
Ikopi echanekileyo yogcino lwedatha ayenzi nje ngokukopa ifayile, kodwa ngeprogram ekhethekileyo. Inkqubo ekhethekileyo ibizwa ngokuba ' ngumcwangcisi '. Ikwaphuhliswa yinkampani yethu ' USU '. Umcwangcisi uyalungiseka. Ungakhankanya iintsuku ezifanelekileyo kunye namaxesha apho ufuna ukwenza ikopi yedatabase.
Kungcono ukuthatha ikopi yonke imihla. Gcina ikopi. Emva koko yongeza umhla okhoyo kunye nexesha kwigama logcino olunesiphumo ukuze wazi kakuhle ukuba ikopi nganye ivela phi. Emva koko, i-archive ebizwa ngokuba yi-archive ikopishwa kwezinye iindawo ezifanayo kwenye indawo yokugcina. Zombini i-database esebenzayo kunye neekopi zayo akufanele zigcinwe kwidiski enye. Ayikhuselekanga. Kwi-hard drive eyahlukileyo, kungcono ukuba neekopi ezininzi zedatha ukusuka kwimihla eyahlukeneyo. Le yindlela ethembeke ngayo. Kungokuchanekileyo ngokwale algorithm ukuba inkqubo ' yoMcwangcisi ' yenza ukhuphelo kwindlela ezenzekelayo. Yile ndlela ikopi ethembekileyo yesiseko sedatha eyenziwa ngayo.
Unakho uku-odola ukukopa okuthembekileyo nokuchanekileyo kwe-database ngoku.
Njengokongeza, unokuphinda u-odole ukubekwa kwedatha efini . Oku kunokugcina inkqubo yakho ukuba ikhompyuter yakho iyaphuka.
