Izifundo ezikhethiweyo

Nawuphi phando ukubona iimpawu zezinto ukuze kucaciswe nokuvavanya ubudlelwane obunentsingiselo kunye nonxibelelwano phakathi kwezalathisi bezi propati.

Obungcali iquka izinto ezahlukeneyo kwizakhiwo zabo ngendlela ethile kwiinkalo ezithile zihlobene. Imisebenzi Isigqibo lokuprograma luqala ukufunda kwisifundo.

Obungcali - le yinxalenye yehlabathi yokwenene, engenamda kwaye iqulethe iinkcukacha ezibalulekileyo kunye engabalulekanga. I umphandi kufuneka akwazi ukwaba inxalenye ebalulekileyo kuzo. Umzekelo, ekusombululeni ingxaki-mboleko, iza kuthathwa yonke ingcaciso efanelekileyo malunga nobomi yabucala umxhasi (nokuba kukho umsebenzi kunye iqabane, abantwana abancinane ukuba umthengi kuzisa, imfundo iinkonzo, njalo njalo). Kwaye ukuze zokusombulula eminye imisebenzi enxulumene nemisebenzi zebhanki, data ezinjalo ziya kuba yinto enkulu. ukubaluleka Data ixhomekeke koko ukhethe njengoko kwisifundo.

Ngexesha isifundo, kufuneka udale umfuziselo ithambeka. Ulwazi oluvela kwimithombo eyahlukeneyo kufuneka ngokusemthethweni. Ligxininise ngokusemthethweni ngokusebenzisa nayiphi na indlela. Funds yahluke kakhulu. Oku kungaba incazelo yombhalo wedomeyini okanye ubhalo ezizodwa lomzobo. Ngenxa model domain uchaza iinkqubo ezithi zenzeke ngayo, kwakunye data balo mmandla uphononongwayo zezifundo.

Ingxelo ingxaki nayo inkcazelo ukuziphatha static kunye olutshintshayo izinto ukuba siphande. Inkcazelo ukuziphatha static ibandakanya iimpawu zezinto kunye nemihlaba yazo. Xa echaza indlela eshukumayo oonobangela izinto yokuziphatha.

Ukuziphatha olutshintshayo lezinto udla ngokuchazwa kunye nokuziphatha static.

Ngamanye amaxesha domain kunye nocazululo umsebenzi adityaniswa inyathelo elinye.

Inyathelo yokufumanisa nokuhlalutya iimfuno data wenza data ngumzekelo ezifunekayo Mining Data. Ngenxa yesi sifundo iingxaki nokwabiwa abasebenzisi; okuhlalutya iimpawu le nkqubo; kwimiba yokufikelela ingcaciso eyimfuneko ukuze uhlalutyo.

Obungcali ihlaziya lula kwaye zinempumelelo ethe kratya xa umbutho ibuyisele indawo yokugcina data. Noko ke, asingabo bonke iinkampani babe enjalo yokugcina data. Kulo mzekelo, umthombo wedatha wokuqala iinkcukacha zokusebenza, reference yaye yokugcina izinto, oko kukuthi, i-data evela (iinkqubo zengcaciso) esele zikhona.

Ulwazi oluninzi ukuze evela EC iintloko kwimithombo yangaphandle nangaphakathi, amaxwebhu iphepha ezahlukeneyo, kwakunye nolwazi lobungcali kunye / okanye iziphumo uvote.

Kufuneka wazi ukuba inkqubo developers software yokulungiselela data kufuneka achaze kangangoko njengemiba kunokwenzeka eziphembelela ngayo inkqubo. Kusenokubakho ezinye data iikhowudi. Ngokomzekelo, omnye iimpawu umxhasi - kwinqanaba yengeniso, nto leyo enokuthi ichazwe: liphantsi kakhulu, ephantsi, ephakathi, phezulu, phezulu kakhulu. Kulo mzekelo, kuyimfuneko ukuqinisekisa inqanaba iqondo yengeniso.

Ekumiseleni isixa ilungelo data kufuneka ithathele ingqalelo odolo data.

Kwimeko ukuba odolwa, kuyimfuneko ukwazi ukuba zibandakanywe iseti idatha yecandelo onyaka / nokungazinzi koqoqosho. Xa abayi-odolwa, ie, iseti kweziganeko ukusuka kuvimba akunanto yakwenza amxesha, ngoko ngethuba yokuqokelela kufuneka bathobele le migaqo ilandelayo:

1) inani elincinane iirekhodi kwiziko ledatha kunokuba unobangela ukudala imodeli ngokwaneleyo;

2), ukuchaneka ongumzekelo iphuculwe ngokwandisa inani data;

3) data endala ngaphandle kwisethi;

4) ubuchule ezisetyenziswa ukwenza imodeli kunye iinkcukacha elikhulu kunene, kufuneka babe nako ukwenza nkulu.
