Ingabe zikhona izifundo zamahhala ze-inthanethi zokuhlaziya idatha? Yebo, zikhona! Lezi zifundo azizuzisi nje ngoba zimahhala, noma ngoba ziku-inthanethi futhi ziyazihambela kodwa qagela ukuthi yini? Basezingeni eliphezulu!

Njengoba ukuhlaziya idatha kuyisici esibalulekile sebhizinisi, kunesidingo esikhulayo sochwepheshe bokuhlaziya idatha. Ukuvela kobuchwepheshe kanye nokwanda kwansuku zonke kwezinqumo ezincike kudatha nakho kube yisibonelo.

Ngokuphazima kweso, ukuhlaziya idatha kubonakala kuyisihloko esishisayo, kukushiya uzibuza ukuthi kuyini. Awudingi ukubheka phambili; I-World Scholars Hub inezixazululo ezinhle kakhulu!

Kuyini Idatha Yezibalo?

Ukuhlaziywa kwedatha yigama elijwayelekile lezinhlobo ezahlukahlukene zokuhlaziywa kwedatha. Ibhekene nokusetshenziswa kwemininingwane etholakalayo namathrendi ukuxazulula inkinga ethile. Ngamagama alula, ukuhlaziywa kwedatha kuphathelene nokuhlaziya idatha noma izibalo ngendlela ehlelekile.

Ngokusekelwe ekuqondeni nasekusetshenzisweni kwamaphethini edatha, ukuhlaziya idatha kufika ekugcineni lapho kwenziwa khona isinqumo esisebenza ngempumelelo ngokwesayensi. Ngokwesayensi ngomqondo wokuthi idatha kufanele idlule ezinyathelweni nezinqubo ezahlukahlukene ngaphambi kokuthi kuthathwe isinqumo.

Noma yiluphi uhlobo lolwazi lungafakwa ngaphansi kokuhlaziywa kwedatha njengoba kuyimfihlo yokuthuthukisa ukusebenza, ukukhulisa inzuzo, kanye nokuthathwa kwezinqumo okunembile kuwo wonke amabhizinisi.

Enye into enhle mayelana nokuhlaziywa kwedatha ukwehlukahlukana kwayo kwemisebenzi. Ngezibalo zedatha, ungaba umhlaziyi wedatha, umhlaziyi wezobuhlakani bebhizinisi, usosayensi wedatha, unjiniyela wedatha, umhlaziyi wokusebenza, umphathi wephrojekthi, noma izibalo zezinhlelo ze-IT, uma sibala ezimbalwa.

Kunezinyathelo ezihlukahlukene ezihilelekile ekuhlaziyweni kwedatha, futhi zonke lezi ngezentuthuko yebhizinisi. Ngasinye salezi zigaba sinokhiye ekusebenzeni kahle kwebhizinisi.

Yiziphi Izinyathelo Ezihilelekile Ekuhlaziyweni Kwedatha?

Ngezansi izinyathelo ezi-4 ezibandakanyekayo ekuhlaziyweni kwedatha:

1. Izibalo ezichazayo:

Izibalo ezichazayo ziphathelene nokuthi ibhizinisi lihamba kahle kangakanani. Umbuzo ovame ukubuzwa kulesi sigaba uthi "Kwenzekani ebhizinisini lakho?"
