UkuQinisekisa kwiLizwe Lwenene
Ukugcinwa kweenkcukacha ngokuqhelekileyo yenye yeenkomo ezingcwele zophuhliso lwesicelo. Yonke ikhosi yeprogram yezifundo oyithathileyo okanye incwadi oyifunayo mhlawumbi uyashumayela ukubaluleka kokuqulunqwa kwemigangatho yolwazi .
Ixesha locelomngeni le nto. Ngamanye amaxesha kulungile ukubeka uphawu lweziko lakho!
Xa kufuneka Ulungelelanise?
Ukugcinwa kwedatha ngokubanzi kukukhusela ingqibelelo yakho yedata. Ingcinga ephakamileyo kwiimeko ezininzi, kwaye kufuneka uqale nayiphi na isicwangciso senkcazelo yolwazi ngokusebenza ngokusemgangathweni engqondweni. Ukuba unokwenza i-database yakho ifake, yenza oko! Enyanisweni, Nazi ezinye iingcebiso ezichanekileyo malunga nendlela yokugcina ifowuni yakho kule ndawo:
- Ukubeka i-Database Yakho kwiFom yeSiqhelo sokuQala (1NF)
- Ukubeka i-Database yakho kwifomu yesiBini yesiQhelo (2NF)
- Ukubeka i-Database yakho kwifomu yesithathu eqhelekileyo (2NF)
Umgca wecala kukuba kufuneka ulungelelanise isiseko sakho sedatha ngaphandle kokuba unesizathu esihle kakhulu sokwenza njalo. Ukuqhelanisa ngokuqhelekileyo kuqhelekileyo kuyindlela yokuyila eyiyo. Iyanciphisa ulwazi olungapheliyo, lugcizelela ukusebenza kwaye linciphisa amathuba okuba uza kuba neengxaki zengqibelelo yedatha ezibangelwa ukuba neenkcukacha ezifanayo ezigqityiweyo kwiinkalo ezahlukeneyo zeenkcukacha zakho.
Ezinye izizathu ezifanelekileyo zokungagqibekanga
Oko kwathiwa, zikho izizathu ezifanelekileyo zokungagqithisi ukugcina idatha yakho. Makhe sibone ezimbalwa:
- Ukudibanisa kubiza . Ukuqhelanisa i-database yakho kubandakanya ukudala amatafula amaninzi.

- Ukuba usebenzisa i-NoSQL yedatha , ukusekwa kwendabuko akunqwenelekayo. Kunoko, qulunqa i-database yakho usebenzisa umzekelo weBASE oxolela kakhulu. Oku luncedo xa ugcina idatha engaqinisekisiwe njengama-imeyili, imifanekiso okanye iividiyo.
Amanye amazwi okulumkisa
Ukugcinwa kweenkcukacha ngokuqhelekileyo ngokuqhelekileyo kuluvo oluhle. Kufuneka uzame ukulandela imigaqo yokuqhelanisa xa kubonakala kunengqondo ukwenza njalo. Kodwa ukuba zonke izikhombisi zibonisa ukuba zimeleleka kunzima ukuphumeza, cinga indlela eya kufumana umsebenzi ngelixa ukhusela idatha yakho.
Ekugqibeleni - ukuba ukhetha ukulahleka kwimimiselo yokuqhelanisa, qaphela ngakumbi malunga nendlela uqinisekisa ngayo ukuthembeka kweenkcukacha. Ukuba ugcina ulwazi olungapheliyo, faka iziphumo kunye nezinye izilawuli endaweni ukuze uqinisekise ukuba ulwazi luhlala luhambelana.
