Lezi zici kufanele zi-odwe ngokwehlukana.
Akekho kithi ocabanga ngezinto ezimbi kuze kube yilapho kwenzeka okuthile okubi. Bese kuqala ukuzisola kanye nenkulumo mayelana nokuthi yini ebesingayenza ukukunqanda. Siphakamisa ukuthi singalindi kuze kushaye izulu. Ake siqonde esihlokweni esibaluleke kakhulu ' sokugcinwa kolwazi '. Ukuthola ulwazi yikho okumele kwenziwe khona manje ukuze kungashiywa yisikhathi. I-'Universal Accounting System ' ingaqinisekisa ukuphepha nokuvikeleka kolwazi. Kodwa kulokhu udinga ukuthatha izinyathelo ezithile.
Ukulondolozwa kwedatha kufinyelelwa ngokukopisha isizindalwazi. Ikhophi yasenqolobaneni iyikhophi egciniwe yohlelo olusebenzisa isizindalwazi. Ngokuvamile, i-database isetshenziswa yinoma yiluphi uhlelo ngandlela thize olusebenza nolwazi. Ukusebenzisa isizindalwazi kusho ukusebenzisana nolunye uhlelo olubizwa ngokuthi ' isistimu yokuphathwa kwedathabhe '. Kufushaniswe njengokuthi ' DBMS '. Futhi inkinga ukuthi awukwazi ukwenza ikhophi ngokumane ukopishe amafayela ohlelo. Ikhophi yasenqolobaneni yedathabheyisi kufanele yenziwe kusetshenziswa izingcingo eziyisipesheli zohlelo lokuphathwa kwedathabhesi .
Uhlelo lusebenza kuseva. Iseva i-hardware . Njenganoma iyiphi i-hardware, iseva ayihlali unomphela. Noma yimuphi umshini unomkhuba omubi wokuwohloka ngesikhathi esingafanele. Yebo, lokhu kuyihlaya. Asikho isikhathi esifanele sokuphuka. Akekho kithi olinda okuthile esikusebenzisayo ukuba kuphuke.
Kuba buhlungu kakhulu lapho isizindalwazi sinqamuka. Lokhu kuyivelakancane kakhulu, kodwa kuyenzeka. Ikakhulukazi ngenxa yokunqamuka kukagesi kungazelelwe. Isibonelo, enye idatha ifakwe ku-database, futhi ngaleso sikhathi amandla avalwa ngokuzumayo. Futhi awunakho ukunikezwa kwamandla okungaphazamiseki. Kuzokwenzekani kuleli cala? Kulokhu, ifayela lesizindalwazi lizoba nesikhathi sokugcwalisa kancane kuphela lonke ulwazi ozame ukuyengeza. Ukurekhoda ngeke kuqedele kahle. Ifayela lizophulwa.
Esinye isibonelo. Ukhohlwe ukufaka i-antivirus. Kubanjwe igciwane ku-inthanethi elingena esikhundleni, elibhala ngemfihlo, noma elimane lonakalise amafayela ohlelo. Yilokho kuphela! Ngemva kwalokho, ngeke futhi ukwazi ukusebenzisa uhlelo olunegciwane.
Kwenzeka ukuthi ngisho izenzo zabasebenzisi zingonakalisa isofthiwe. Kunezinhlobo ezimbili zesenzo esinonya: ongahlosile nongenhloso. Okusho ukuthi, noma umsebenzisi wekhompiyutha ongenalwazi ngokuphelele angenza okuthile okuzolimaza uhlelo ngokungazi. Noma, ngokuphambene nalokho, umsebenzisi onolwazi angalimaza ngokuqondile inhlangano, isibonelo, uma kwenzeka ukuxoshwa lapho kukhona ukungqubuzana nenhloko yebhizinisi.
Endabeni yefayela elisebenzisekayo lohlelo, elinesandiso esithi ' EXE ', konke kulula. Kuyokwanela ukuthi uqale ukopishe leli fayela kanye endaweni yokugcina yangaphandle, ukuze kamuva uhlelo lubuyiselwe kulo uma kwenzeka kuba nokwehluleka okuhlukahlukene.
Kodwa lokhu akunjalo nge-database. Ayikwazi ukukopishwa kanye ekuqaleni komsebenzi ngohlelo. Ngoba ifayela le-database liyashintsha nsuku zonke. Nsuku zonke uletha amakhasimende amasha nama-oda amasha.
Futhi, ifayela lesizindalwazi alikwazi ukukopishwa njengefayela elilula. Ngoba ngesikhathi sokukopisha i-database ingase isetshenziswe. Kulokhu, lapho ukopisha, ungagcina unekhophi ephukile, ongeke ukwazi ukuyisebenzisa uma kwenzeka ukwehluleka okuhlukahlukene. Ngakho-ke, ikhophi evela ku-database yenziwa ngokuhlukile. Wonke umuntu udinga ikhophi efanele yesizindalwazi.
Ikhophi efanele ye-database ayenziwa nje ngokukopisha ifayela, kodwa ngohlelo olukhethekile. Uhlelo olukhethekile lubizwa nge- 'Scheduler '. Iphinde ithuthukiswe yinkampani yethu ' USU '. Isihleli siyalungiseka. Ungacacisa izinsuku nezikhathi ezifanele lapho ufuna ukwenza ikhophi yesizindalwazi.
Kungcono ukuthatha ikhophi nsuku zonke. Faka kungobo yomlando ikhophi. Bese wengeza idethi yamanje nesikhathi egameni lengobo yomlando ewumphumela ukuze wazi kahle ukuthi ikhophi ngayinye isuka kuluphi usuku. Ngemva kwalokho, ingobo yomlando eqanjwe kabusha ikopishelwa kwezinye izingobo zomlando ezifanayo kwenye indawo yokugcina. Kokubili i-database esebenzayo namakhophi ayo akufanele agcinwe kudiski efanayo. Akuphephile. Ku-hard drive ehlukile, kungcono ukuba namakhophi amaningana e-database kusukela ngezinsuku ezahlukene. Yile ndlela ethembeke ngayo kakhulu. Kungokwalesi simiso se-algorithm lapho uhlelo lwe- 'Scheduler ' lenza ikhophi ngemodi ezenzakalelayo. Lena yindlela ikhophi ethembekile ye-database eyenziwa ngayo.
Ungakwazi uku-oda ukukopishwa okuthembekile nokulungile kwesizindalwazi njengamanje.
Njengokwengeza, ungakwazi futhi uku-oda ukubekwa kwesizindalwazi emafini . Lokhu kungase futhi kulondoloze uhlelo lwakho uma ikhompuyutha yomuntu siqu iphuka.
Bona ngezansi ukuze uthole ezinye izihloko eziwusizo:
I-Universal Accounting System
2010 - 2024
