Ukujwayelekile kwizwe eliyiqiniso
Ukumiswa kwedatha ingenye yezinkomo ezingcwele zokuthuthukiswa kwesicelo. Yonke inkambo yokuhlela i-undergraduate oyithathile noma incwadi oyifundayo cishe iyashumayela ukubaluleka kokujwayelekile kwezingqinamba.
Sekuyisikhathi sokuba inselele lokho okushoyo. Ngezinye izikhathi kulungile ukubeka phansi imininingwane yakho!
Kufanele Uzigcine Nini?
Ukusetshenziswa kwedatha yokuvikela idatha kuvikela ubuqotho bwedatha yakho. Umqondo omuhle ezimweni eziningi, futhi kufanele uqale noma yikuphi ukuklanywa kwe-database ngokusebenza ngokujwayelekile kumqondo. Uma ungakwazi ukuvamisa i-database yakho, hamba! Eqinisweni, Nansi iseluleko esisebenzayo sendlela yokulungisa idatha yakho kulesi sayithi:
- Ukubeka I-Database Yakho KuFomu Lokuqala Elijwayelekile (1NF)
- Ukubeka Idatha Yakho Kwifomu Yesibili Ejwayelekile (2NF)
- Ukubeka Idatha Yakho KuFomu Eliyisithathu Elijwayelekile (2NF)
Okubalulekile ukuthi kufanele uvuselele i-database yakho ngaphandle kokuthi unesizathu esihle kakhulu sokwenza kanjalo. Ukuziqhenya ngokuvamile kuvame ukuklama ukuklama. Iyanciphisa ulwazi olulinganiselwe, lwenza ngcono ukusebenza futhi linciphisa amathuba okuthi uzoba nezinkinga zokuthembeka kwedatha ezibangelwa ukuthi ube nedatha efanayo ephawulwe emaceleni ahlukene wedatha yakho.
Ezinye Izizathu Ezihle Ukuthi Ungagcini
Lokho kusho, kunezizathu ezithile ezinhle zokungavumelanisa idatha yakho. Ake sibheke ezimbalwa:
- Ukujoyina kuyabiza . Ukunciphisa imininingwane yakho ngokuvamile kuhilela ukudala amatafula amaningi. Empeleni, ungakwazi ukuphefumula kalula ngalokho ocabanga ukuthi kufanele kube umbuzo olula obeka amatafula amahlanu noma ayishumi. Uma uke wazama ukwenza ukujoyina kwetafula elihlanu, uyazi ukuthi isebenza ngokuyisisekelo, kodwa ihamba kancane kancane ekusebenzeni. Uma ukwakha uhlelo lokusebenza lwewebhu oluthembele kumbuzo amaningi wokujoyina amathebula amakhulu, ungase uthole ucabanga ukuthi, "Uma ngabe le database ingavamile!" Uma uzwa lo mqondo ekhanda lakho, yisikhathi esihle cabanga ngokudumisa. Uma ungakwazi ukunamathela yonke idatha esetshenziselwa leyo mibuzo ngaphakathi kwetafula elilodwa ngaphandle kokufaka ingozi empilweni yakho yedatha, hamba! Yiba yisigebengu bese ubeka phansi imininingwane yakho. Ngeke ubuke emuva!
- Ukuklama okujwayelekile kunzima . Uma usebenza nge-database eyinkimbinkimbi yezibalo , cishe uzothola ukushaya ikhanda lakho ngokumelene netafula phezu kokubunzima kokujwayelekile. Njengombuso olula wesithupha, uma usebenzisa usuku lonke uzama ukuthola indlela yokuhambisa ifomu lesine elivamile, ungase uthathe ukujwayelekile ngokude kakhulu. Hamba emuva bese uzibuza ukuthi kuwufanele ngempela ukuqhubeka.
- Okusheshayo nokungcolile kufanele kusheshe futhi kungcolile . Uma uvele uthuthukise isibonisi, yenza nje noma yini esebenza ngokushesha. Ngempela. Kulungile. Ukuthuthukiswa kwesicelo okusheshayo ngezinye izikhathi kubaluleke kakhulu kuneklamo enhle. Khumbula ukubuyela emuva futhi ubheke ngokucophelela umklamo wakho uma usulungele ukuhambisa ngaphesheya kwesigaba sokuphikisa. Intengo oyikhokhayo yokuklanywa kwemininingwane esheshayo neyungcolile yukuthi kungase kudingeke uyilahle futhi uqale uma sekuyisikhathi sokwakha ukukhiqiza.
- Uma usebenzisa i-database ye-NoSQL , ukujwayelekile kwendabuko akuyona efiselekayo. Esikhundleni salokho, yakha i-database yakho usebenzisa imodeli ye- BASE okuthethelela kakhulu. Lokhu kuyasiza uma ugcina idatha engakhiwe njengama-imeyili, izithombe noma amavidiyo.
Amanye Amazwi Wokuqapha
Ukusetshenziswa kwe-database ngokuvamile kuyisimo esihle. Kufanele uzame ukulandela imigomo yokujwayelekile uma kubonakala kunengqondo ukwenza kanjalo. Kodwa uma zonke izinkomba zikhomba ukujwayelekile ukuthi ziyinkimbinkimbi kakhulu ukuze ziqaliswe, cabanga indlela ezokwenza umsebenzi ufeze ngenkathi uvikela idatha yakho.
Okokugcina - uma ukhetha ukwehla emithethweni yokujwayelekile, qaphela ngokucacile ukuthi ubeka kanjani ukuthembeka kwesisekelo sedatha. Uma ugcina ulwazi oluvulekile, faka izimbangela nezinye izilawuli endaweni ukuze uqinisekise ukuthi ulwazi luhlala luvumelana.
