Esihlokweni sizochaza yini i-oracle kanye nezici zayo njengethuluzi lokugcinwa noma ukuthuthukiswa kwedathabheyisi.
I-Oracle, yaphumelela kakhulu ezinkampanini kangangokuba yakwazi ukufakwa ohlwini kuWall Street Stock Exchange
Yini i-Oracle?
Kuyisiteji esisetshenziselwa ukwakha noma ukuphatha ngempumelelo amasistimu wedatha. Ngenye yezinto ezinhle kakhulu emakethe yamathuluzi eseva, ngakho-ke, ijwayele ukusetshenziselwa izinkampani ezifuna ukutshala imali ezinhlelweni zazo zedatha.
Isebenza nesixhumi esibonakalayo somsebenzisi nesiphakeli, okusho ukuthi, isenzo siyacelwa noma senziwa futhi iseva inikeza impendulo, ivumela umsebenzisi ukuthi abeke isicelo. Uhlelo alusakazeki kangako kweminye imininingwane, ngoba luphethwe izinkampani ezinesifiso sokutshala imali kulwazi lwazo.
Iyamangalisa kunezinye izinhlelo ngenxa yamakhono ayo, phakathi kokuyinhloko ukusekelwa kwayo kwe-multiplatform, okuvumela ukusebenza ngamazinga ahlukene nangamanani ahlukile wedatha.
Isebenza kanjani i-Oracle?
I-Oracle iyithuluzi noma uhlelo lokusebenza, ngakho-ke, kufanele ilandwe ngaphandle ukuze ijabulele imisebenzi yayo. Njengokwesekwa noma ukuxhumana, isebenzisa ulimi oluthile lokuqamba; PL / SQL.
I-PL / SQL ilulimi lohlelo olusebenzisa isakhiwo esifana ne-SQL, noma kunjalo, ithuthukisa izici zayo. Ingaphatha inani elikhulu lokuguquguqukayo, okungukuthi, amakhodi nedatha ephelele.
I-PL / SQL nayo ine-othomathikhi yokulawula usongo, ephikisana nayo ngokwayo ukuhlaselwa kwanoma iyiphi i-ejenti eyingozi ku-database. Ilungele uhlelo lwe-Oracle, ngakho-ke izolungiswa kangcono kunanoma iyiphi enye ithuluzi lokuphatha idatha.
Ulimi lwe-SQL lusasebenza ngethuluzi le-Oracle, noma kunjalo, i-PL / SQL ingcono kulolu hlobo lwensizakalo, ngoba ithuthukisa ukugcinwa kwedatha kangcono. I-Oracle ibuye isebenzise i-SQL plus, iseva evikelayo yedatha futhi isebenzisa i-SQL efanayo njengesisekelo.
Ulimi lwayo luvumela iseva yedatha ukuthi ivuselelwe kaningi ngangokunokwenzeka, ikwazi ukubuyekeza njalo lapho inkampani iyidinga.
Yimaphi amathuluzi asetshenziswa yi-Oracle?
Njengoba sekuchaziwe vele, ithuluzi layo eliyinhloko ulimi lwayo lwe-PL / SQL, isikhombimsebenzisi sezizukulwane ezintsha, kepha inezinye izinhlobo zezinto ezenza ukuthi ibe yinye yezinhloko emakethe. I-Oracle ingakhiqiza futhi iphathe amafomu, atholakala kuseva.
Amafomu, phambilini, avumela abasebenzisi abahlukahlukene ukuthi babambe iqhaza ekuhleleni idokhumenti, noma kunjalo, amadokhumenti enziwe agcinwa kudiski, kufolda eyenziwe uhlelo, ngakho-ke, kufanele ufake ifolda bese uhlela idokhumenti Ukusuka lapho. Konke lokhu bekubucayi futhi kunzima kakhulu, ikakhulukazi ngokuthuthuka kwezinhlelo ze-Oracle, ezingasenzeki.
Ukuthuthuka kwamafomu kubonga uMklami, okungavumeli kuphela abaningana ukuthi basebenzise noma baphathe ifayili ngaphandle kwezinkinga, ngasikhathi sinye, kuvumela uhlelo ukuthi luphelele futhi luzole, ngaphandle kwanoma yiluphi uhlobo lwesithiyo, njengokungathi kusetshenziswa uhlelo olunqunyelwe kusengaphambili ngakho.
Kodwa-ke, uMklami akanikeli ukulungiswa okuhle kokubuka noma ukuhlelwa okuphelele kwemibhalo, ngenxa yala mathuluzi afana nonjiniyela. Yize, uMqambi, engenazo izinzuzo ukuze abambalwa bakwazi ukuhlela idokhumenti, inikeza amatafula nokwakhiwa osekuvele kulungiselelwe amafomu.
Izici ze-Oracle
I-Oracle, ikuvumela ukuthi ubuke amafomu akho ngendlela ephelele nange-interface ehlanzekile, ngenxa yokuthi inokulawulwa okuphelele nokusha kokuqhafaza. Ngaphezu kwalokho, kuvumela umsebenzisi ukuthi azi inani ledatha elingenayo nelishiyayo.
Inesistimu yokuphepha ephelele, evikela ngokuphelele yonke idatha egcinwe kuseva. Ngaphezu kwalokho, inikeza isipele ukuvikela yonke imininingwane.
Inikeza ukusabalalisa, okungukuthi, ithuluzi livumelanisa nokusebenza kwenkampani, ngaphandle kokulahlekelwa ikhwalithi ephezulu noma izici ezikhethekile. Futhi, ithuthukisa uhlelo ukuze inkampani isebenze kahle ekusetshenzisweni kwayo futhi ngaleyo ndlela ibe nomkhiqizo omkhulu.
Isici esibalulekile ukuthi abasebenzisi bangabaphathi abakhulu noma abenethonya lohlelo lokusebenza, ngoba bangalivumelanisa nezidingo zabo, ngaphezu kwalokho, isikhombimsebenzisi sayo silula kakhulu ukusisebenzisa.
Umsebenzisi ngeke kudingeke akhathazeke ngokuthi ngubani ongena kuseva futhi azame ukungena ukubona amafayela atholakalayo, ngoba anokulawulwa kokufinyelela. Ukulawulwa kokufinyelela kuphatha ukungena komuntu ngamunye ku-database futhi kugcina imali yabo ukuze umphathi azi.
Kuthuthukile futhi kuphelele ezinkampanini ezifuna ukuvikela amafayela azo noma zazi ukuthi kwenzekani. Uhlelo ngeke lugcwale idatha futhi uzokwazi ukungena kusuka noma yikuphi.
I-Oracle, noma kungeyona eyezizukulwane ezintsha, ingalandwa noma ihambisane nanoma yiluphi uhlelo lokusebenza lwezizukulwane ezintsha.
Uma uyithandile le ndatshana, ngikumema ukuba ufunde ngayo "Amathuluzi eskram wokuphathwa kwephrojekthi", okuthunyelwe okuphelele nokuchazayo ukuthi la mathuluzi akusiza kanjani ukuphathwa kwephrojekthi.
