Chifukwa Chimene Kuyeretsa Kwa Data Ndikofunikira komanso Momwe Mungagwiritsire Ntchito Njira ndi Mayankho a Ukhondo wa Data

Kuyeretsa Deta: Momwe Mungayeretsere Zambiri Zanu

Kusakwanira kwa data ndi nkhawa yomwe ikukulirakulira kwa atsogoleri ambiri azamalonda chifukwa amalephera kukwaniritsa zomwe akufuna. Gulu la osanthula deta - omwe akuyenera kupanga chidziwitso chodalirika - amathera 80% ya nthawi yawo kuyeretsa ndi kukonza deta, ndi 20% yokha ya nthawiyo yatsala kuti ipange kusanthula kwenikweni. Izi zimakhudza kwambiri zokolola za gulu chifukwa amayenera kutsimikizira pamanja mtundu wa data wamagulu angapo.

84% ya ma CEO akuda nkhawa ndi kuchuluka kwa deta yomwe akutengera zisankho zawo.

Akakumana ndi zovuta zotere, mabungwe amayang'ana njira yokhazikika, yosavuta, komanso yolondola kwambiri yoyeretsera ndikuyimitsa deta. Mu blog iyi, tiwona zina mwazinthu zofunika pakuyeretsa deta, ndi momwe mungawagwiritsire ntchito.

Kodi Data Cleansing N'chiyani?

Kuyeretsa deta ndi mawu otakata omwe amatanthauza njira yopangira deta kuti igwiritsidwe ntchito pazifukwa zilizonse. Ndi ndondomeko yokonza khalidwe la deta yomwe imachotsa mauthenga olakwika ndi osayenera kuchokera kumagulu a data ndi zikhalidwe zokhazikika kuti zitheke kuwona bwino kuzinthu zonse zosiyana. Ntchitoyi nthawi zambiri imakhala ndi izi:

  1. Chotsani ndi kusintha - Minda yomwe ili m'gulu la data nthawi zambiri imakhala ndi zilembo zotsogola kapena zotsatizana kapena zizindikiro zopumira zomwe zilibe ntchito ndipo zimafunika kusinthidwa kapena kuchotsedwa kuti ziwunikidwe bwino (monga mipata, ziro, zodula, ndi zina). 
  2. Phatikizani ndi kuphatikiza - Nthawi zina minda imakhala ndi zinthu zophatikizika, mwachitsanzo, Address munda uli Nambala WamsewuDzina la StreetmaganizoState, ndi zina zotero. Zikatero, minda yophatikizika iyenera kugawidwa m'mizere yosiyana, pamene zigawo zina ziyenera kuphatikizidwa pamodzi kuti muwone bwino deta - kapena chinachake chomwe chimagwira ntchito yanu.
  3. Sinthani mitundu ya data - Izi zimaphatikizapo kusintha mtundu wa data pamunda, monga kusintha Nambala yafoni munda umene unalipo kale Mzere ku Number. Izi zimatsimikizira kuti zonse zomwe zili m'mundawu ndi zolondola komanso zovomerezeka. 
  4. Tsimikizirani machitidwe -Magawo ena akuyenera kutsata ndondomeko yoyenera kapena mawonekedwe. Chifukwa chake, njira yoyeretsera deta imazindikira machitidwe apano ndikusintha kuti zitsimikizire zolondola. Mwachitsanzo, a Foni yaku US Number kutsatira chitsanzo: AAA-BBB-CCCC
  5. Chotsani phokoso - Magawo a data nthawi zambiri amakhala ndi mawu omwe sawonjezera phindu, chifukwa chake, amayambitsa phokoso. Mwachitsanzo, lingalirani mayina amakampani awa 'XYZ Inc.', 'XYZ Incorporated', 'XYZ LLC'. Mayina onse amakampani ndi ofanana koma njira zanu zowunikira zimatha kuziwona ngati zapadera, ndipo kuchotsa mawu ngati Inc., LLC, ndi Incorporated kumatha kuwongolera kusanthula kwanu.
  6. Fananizani ndi data kuti muzindikire zobwerezedwa - Ma dataset nthawi zambiri amakhala ndi zolemba zingapo zamabungwe omwewo. Kusiyanasiyana pang'ono kwa mayina amakasitomala kumatha kutsogolera gulu lanu kuti lilembe zambiri munkhokwe yanu yamakasitomala. Dongosolo loyera komanso lokhazikika liyenera kukhala ndi zolemba zapadera - mbiri imodzi pagulu lililonse. 

Zopangidwa motsutsana ndi Zosakhazikika

Chimodzi mwazinthu zamakono za data ya digito ndikuti sizogwirizana ndi nambala kapena mtengo wamawu. Deta yokhazikika ndi yomwe makampani amagwira nawo ntchito - kuchuluka data yosungidwa m'mawonekedwe enaake monga ma spreadsheets kapena matebulo kuti mugwiritse ntchito mosavuta. Komabe, mabizinesi akugwira ntchito ndi data yosasinthika mochulukiranso… izi ndi kuyenera deta.

Chitsanzo cha data yosalongosoka ndi chilankhulo chachilengedwe kuchokera ku mawu, zomvera, ndi makanema. Chimodzi chodziwika bwino pakutsatsa ndikukunkha malingaliro amtundu kuchokera ku ndemanga zapaintaneti. Njira ya nyenyezi idakonzedwa (mwachitsanzo, kuchuluka kwa 1 mpaka 5 nyenyezi), koma ndemangayo siinapangidwe ndipo zofunikira ziyenera kukonzedwa kudzera mu chilankhulo chachilengedwe (NLP) ma algorithms kuti apange kuchuluka kwa malingaliro.

Mungatsimikize Bwanji Deta Yoyera?

Njira yothandiza kwambiri yowonetsetsera kuti deta yanu ndi yoyera ndikuwunika malo aliwonse olowera pamapulatifomu anu ndikusintha mwadongosolo kuti zitsimikizire kuti zalowetsedwa bwino. Izi zitha kuchitika m'njira zingapo:

  • Zofunika magawo - kuwonetsetsa kuti fomu kapena kuphatikiza kuyenera kudutsa magawo enaake.
  • Kugwiritsa ntchito mitundu ya data ya m'munda - kupereka mindandanda yocheperako yosankhidwa, mawu okhazikika kuti apangidwe deta, ndikusunga deta mumitundu yoyenera ya data kuti atsekereze data kuti ikhale yoyenera komanso mtundu wosungidwa.
  • Kuphatikiza kwa ntchito za chipani chachitatu - kuphatikiza zida za chipani chachitatu kuti zitsimikizire kuti deta ikusungidwa bwino, monga gawo la adiresi lomwe limatsimikizira adiresi, lingapereke deta yokhazikika, yabwino.
  • Kuvomereza - Kukhala ndi makasitomala anu kutsimikizira nambala yawo ya foni kapena imelo adilesi kungatsimikizire kuti zolondola zasungidwa.

Malo olowera sikuyenera kukhala mawonekedwe, ayenera kukhala cholumikizira pakati pa dongosolo lililonse lomwe limadutsa deta kuchokera kudongosolo lina kupita ku lina. Makampani nthawi zambiri amagwiritsa ntchito nsanja kuchotsa, kusintha, ndi kutsitsa (ETL) data pakati pa machitidwe kuti zitsimikizidwe zoyera zasungidwa. Makampani amalimbikitsidwa kuchita kupeza deta kufufuza kuti alembe malo onse olowera, kukonza, ndi kugwiritsa ntchito deta yomwe ali m'manja mwawo. Izi ndizofunikira pakuwonetsetsa kuti zikutsatira miyezo yachitetezo komanso malamulo achinsinsi.

Kodi Mungayeretse Bwanji Deta Yanu?

Ngakhale kukhala ndi deta yoyera kungakhale koyenera, machitidwe omwe adakhalapo kale komanso kusasamala polowetsa ndi kujambula deta nthawi zambiri amakhalapo. Izi zimapangitsa kuyeretsa deta kukhala gawo lamagulu ambiri otsatsa malonda. Tinayang'ana njira zomwe njira zoyeretsera deta zimaphatikizapo. Nazi njira zomwe bungwe lanu lingagwiritsire ntchito kuyeretsa deta:

Njira 1: Kugwiritsa Ntchito Njira Yotengera Khodi

Python ndi R ndi zilankhulo ziwiri zomwe zimagwiritsidwa ntchito popanga ma coding zothetsera kusokoneza deta. Kulemba zolembedwa kuti muyeretse deta kumatha kuwoneka kopindulitsa popeza mumatha kukonza ma aligorivimu molingana ndi mtundu wa data yanu, komabe, zitha kukhala zovuta kusunga zolembedwazi pakapita nthawi. Kuphatikiza apo, vuto lalikulu kwambiri ndi njirayi ndikulemba njira yokhazikika yomwe imagwira ntchito bwino ndi ma dataset osiyanasiyana, m'malo molemba zochitika zenizeni. 

Njira 2: Kugwiritsa Ntchito Zida Zophatikizira Platform

Mapulatifomu ambiri amapereka mapulogalamu kapena opanda code zolumikizira kusuntha deta pakati pa machitidwe mumtundu woyenera. Mapulatifomu opangira makina ayamba kutchuka kotero kuti nsanja zitha kuphatikiza mosavuta pakati pa zida zamakampani awo. Zida izi nthawi zambiri zimakhala ndi njira zoyambilira kapena zokonzedweratu zomwe zitha kuyendetsedwa pakulowetsa, kufunsa, kapena kulemba deta kuchokera padongosolo lina kupita ku lina. Mapulatifomu ena, monga Njira Zosinthira za Robotic (RPA) mapulaneti, amatha kulowetsanso deta muzithunzi pamene kusakanikirana kwa deta sikukupezeka.

Njira 3: Kugwiritsa Ntchito Artificial Intelligence

Zolemba zenizeni zenizeni ndizosiyana kwambiri ndipo kugwiritsa ntchito zopinga zachindunji m'minda kungapereke zotsatira zolakwika. Apa ndipamene nzeru zopangapanga (AI) zingakhale zothandiza kwambiri. Maphunziro amitundu yolondola, yolondola, ndi yolondola komanso kugwiritsa ntchito zitsanzo zophunzitsidwa pamarekodi omwe akubwera kungathandize kusokoneza zizindikiro, kuzindikira mwayi woyeretsa, ndi zina zotero.

Zina mwazinthu zomwe zitha kukulitsidwa ndi AI pakuyeretsa deta zatchulidwa pansipa:

  • Kuzindikira zolakwika muzambiri.
  • Kuzindikira kudalira kolakwika kwa ubale.
  • Kupeza zolemba zobwereza kudzera mumagulumagulu.
  • Kusankha master records malinga ndi kuthekera kowerengedwa.

Njira 4: Kugwiritsa Ntchito Zida Zapamwamba za Data Yodzithandizira

Ogulitsa ena amapereka ntchito zosiyanasiyana zama data zomwe zimayikidwa ngati zida, monga mapulogalamu oyeretsa deta. Amagwiritsa ntchito ma aligorivimu otsogola m'makampani komanso eni ake polemba mbiri, kuyeretsa, kufananiza, kufananitsa, ndi kuphatikiza zidziwitso kumadera osiyanasiyana. Zida zoterezi zimatha kukhala ngati pulagi-ndi-sewero ndipo zimafuna nthawi yocheperako poyerekeza ndi njira zina. 

Makwerero a Zambiri

Zotsatira za ndondomeko yowunikira deta ndi zabwino monga momwe deta yolowetsera ikuyendera. Pazifukwa izi, kumvetsetsa zovuta zamtundu wa data ndikukhazikitsa njira yomaliza yokonza zolakwikazi kungathandize kuti deta yanu ikhale yaukhondo, yokhazikika, komanso yogwiritsidwa ntchito pazifukwa zilizonse zomwe mukufuna. 

Data Ladder ili ndi zida zopangira zinthu zambiri zomwe zimakuthandizani kuti muchotse zikhalidwe zosagwirizana ndi zolakwika, kupanga ndi kutsimikizira mapatani, ndikupeza malingaliro okhazikika pamagwero onse a data, kutsimikizira kudalirika kwa data, kulondola, ndi kugwiritsidwa ntchito.
