Ukufunyanwa kwezibalo ezisasazwayo
Ehlabathini apho idatha iveliswa ngesantya esiphezulu, ukukwazi ukulawula kunye nokuhlalutya umthamo omkhulu wedatha kuye kwaba yinto efunekayo ukuze ube nesakhono. Uqeqesho "Yenza izibalo ezisasaziweyo kwidatha enkulu" enikezelwa kwi-OpenClassrooms yenzelwe ukukuxhobisa ngezakhono eziyimfuneko ukuze uqonde le ndalo inzima.
Ngethuba lolu qeqesho, uya kwaziswa kwiikhonsepthi ezisisiseko ze-computing esasazwayo. Uya kufunda indlela yokusebenzisa izixhobo ezinamandla ezifana ne-Hadoop MapReduce kunye ne-Spark, eyona nto iphambili kwinkalo yohlalutyo lwedatha enkulu. Ezi zixhobo ziya kukuvumela ukuba uchithe imisebenzi enzima ibe yimisebenzi engaphantsi elawulekayo enokuthi yenziwe ngaxeshanye koomatshini abaninzi, ngaloo ndlela ulungiselela ixesha lokuqhuba kunye nokusebenza.
Ukongezelela, uqeqesho luhamba ngamanyathelo okuhambisa amaqoqo e-computing yefu usebenzisa i-Amazon Web Services (AWS), inkokeli engenakuphikiswa kwi-computing yefu. Nge-AWS, uya kuba nakho ukusungula izibalo ezisasaziweyo kumaqela aqulethe uninzi loomatshini, ngaloo ndlela unikezela ngamandla amakhulu ekhompyuter.
Ngokuzixhobisa ngezi zakhono, awuyi kukwazi ukulawula umthamo omkhulu wedatha kuphela, kodwa uphinde ufumane ulwazi oluxabisekileyo olunokuguqula ukusebenza kunye nezicwangciso zenkampani. Olu qeqesho ke ngoko linyathelo elibalulekileyo kuye nabani na ofuna ukuphuhlisa ikhondo lakhe kwicandelo lenzululwazi yedatha.
Ukwenziwa nzulu koBuchule obukwinqanaba eliphezulu kunye neZixhobo
Uya kuntywiliselwa kwindawo apho ithiyori idibana nokusebenza. Iimodyuli eziqhubela phambili kolu qeqesho ziya kukunceda ube nobuchule obungakumbi bekhompyuter esasazwayo, isakhono esibalulekileyo kwihlabathi lanamhlanje eliqhutywa yidatha.
Uya kwaziswa kwiikhonsepthi eziphambili ngakumbi njengokwakhiwa kwezicelo ezisasaziweyo ezinokusingatha imisebenzi enzima ngokusebenza okumangalisayo. Iiseshoni ezisebenzayo ziya kukunika ithuba lokusebenza kwizifundo zokwenyani, ezikuvumela ukuba usebenzise ulwazi olufumeneyo.
Enye yamandla alolu qeqesho kugxininiso ekusebenziseni i-Amazon Web Services (AWS). Uya kufunda ukuseta nokulawula indawo ye-AWS, ufumane izakhono ezisebenzayo eziya kuba luncedo kwihlabathi lobuchwephesha.
Ukongeza, uya kukhokelwa kwiinkqubo zokuphehlelela ukuhanjiswa kwekhompyuter kuwo wonke amaqela, isakhono esiya kukubeka njengengcali kwintsimi. Uqeqesho lwenzelwe ukuguqula ube yingcali enobuchule, elungele ukwenza igalelo elibalulekileyo kwishishini lesayensi yedatha.
Ukulungiselela uMsebenzi oMpumelelo kwiNzululwazi yeDatha
Izakhono ezifunyenwe ngexesha lolu qeqesho azikho ithiyori kuphela, kodwa zimiliselwe ngokunzulu kwiimfuno zangoku zemarike yomsebenzi kwinkalo yesayensi yedatha.
Kugxilwe ekulungiseleleni umsebenzi onempumelelo, apho uya kuba nakho ukulawula kunye nokuhlalutya idatha enkulu ngesakhono esingenakulinganiswa kunye nokusebenza kakuhle. Uya kuxhotyiswa ukwenza izigqibo ezisekelwe kuhlalutyo olunzima lwedatha, i-asethi enkulu kuyo nayiphi na intlangano yanamhlanje.
Ukongeza, uya kuba nethuba lokuphuhlisa inethiwekhi eyomeleleyo yobuchwephesha ngokusebenzisana neengcali kwintsimi kunye nabalingane abanengqondo efanayo. Olu nxibelelwano lunobungqina bezixhobo ezixabisekileyo kwindlela yakho yomsebenzi wekamva.
Ekugqibeleni, olu qeqesho lulungiselela ukuba ube ngumdlali ophambili kwinkalo yesayensi yedatha, intsimi eqhubeka ikhula kwaye ikhula ngokukhawuleza. Ngemfuno ekhulayo yeengcali ezinezakhono kwicandelo lolawulo lwedatha enkulu, uya kuba kwindawo efanelekileyo yokuthatha amathuba avelayo kwaye wenze umsebenzi ophumelelayo.
Ke, ngokubhalisa kolu qeqesho, uthatha inyathelo elikhulu elisingise kumsebenzi othembisayo, apho maninzi amathuba kunye nokukhula okukhulu.
