Sekumashure kwatinogona kuenda munhoroondo yakawanikwa tinowana vanhu vachishandisa data. Zvinofadza, data inotangira nhamba dzakanyorwa. Mimwe yemienzaniso yekutanga yekuchengeta dhata kubva kuma18,000 2 BC apo madzitateguru edu muAfrica aishandisa mamark pamatanda senzira yekuchengeta mabhuku. Mhinduro 4 ne21 dzichagamuchirwawo. Paive pakati pemakumi maviri emakore, zvakadaro, apo Business Intelligence yakatanga kutsanangurwa sekunzwisisa kwatinoita nhasi. BI haina kupararira kusvika pakupera kwezana ramakore rechiXNUMX.

Zvakanakira zvemhando yedata zviri pachena. 

• chivimbo. Vashandisi vanovimba zviri nani data. “75% yeVatungamiri Haavimbe Nedata Ravo"
• Sarudzo dziri nani. Iwe unozogona kushandisa analytics kupesana nedata kuita sarudzo dzakangwara.  Dhata mhando nderimwe rematambudziko maviri makuru akatarisana nemasangano anotora AI. (Imwe inyanzvi yevashandi seti.)
• Competitive Advantage.  Unhu hwe data hunokanganisa kushanda zvakanaka, basa revatengi, kutengesa uye pasi - mari.

6 Zvinhu Zvikuru zveData Quality

Kana iwe usingakwanise kuvimba nedata rako, ungaremekedza sei zano rayo?

Nhasi, mhando yedata yakakosha kune chokwadi chezvisarudzo zvinoitwa nemabhizinesi neBI maturusi, analytics, kudzidza kwemichina, uye hungwaru hwekugadzira. Pakureruka kwayo, mhando yedata idata iro rinoshanda uye rakakwana. Iwe unogona kunge wakaona matambudziko emhando yedata mumusoro wenyaya:

• CDC's COVID-19 Data Kuvandudza - "Mukufamba kwedenda, CDC yanga ichivandudza nguva, kukwana, uye mhando yedata yakakosha yekupindura."
• Marara mukati, marara kunze; city ​​watchdog inowana maitiro anotambudza ekusavimbika kwemhando yedata - "Chirevo chitsva kubva ku[Chicago] acting inspector general chinoti" data quality nyaya" inokanganisa "chinangwa, mashandisiro uye kuvimbika" kweruzivo runoshandiswa kugovera zviwanikwa, kuyera mashandiro evashandi uye kuongorora zvirongwa zvakawanda.
• GAO inowana nyaya dzemhando yedata panguva yekuburitswa kweVA's EHR - "VA haina kuona kuti mhando yedata yakatamira kune yayo itsva Cerner EHR system."

Mune dzimwe nzira - kunyangwe kusvika mugumi rechitatu reBusiness Intelligence - kuwana nekuchengetedza mhando yedata kwakatonyanya kuoma. Mamwe ematambudziko anobatsira mukurwira nguva dzose kuchengetedza mhando yedata anosanganisira:

• Kubatanidzwa uye kutora kunoedza kuunza pamwechete akasiyana masisitimu, maitiro, maturusi uye data kubva kune akawanda masangano. 
• Internal silos yedata pasina zviyero zvekuyananisa kubatanidzwa kwedata.            
• Cheap kuchengetedza yakaita kuti kutora uye kuchengetwa kwehuwandu hwe data kuve nyore. Isu tinotora data yakawanda kupfuura yatinogona kuongorora.
• Iyo yakaoma yedata system yakakura. Kune mamwe ma touchpoints pakati peiyo system yerekodhi panopinzwa data nenzvimbo yekushandisa, ingave iyo yekuchengetera data kana gore.

Ndezvipi zvikamu zve data zvatiri kutaura nezvazvo? Ndezvipi zvimiro zve data zvinobatsira kune kunaka kwayo? Pane zvinhu zvitanhatu zvinobatsira pamhando yedata. Imwe neimwe yeiyi dzidziso yakazara. 

• Timeliness
  • Data yakagadzirira uye inoshandiswa kana ichidiwa.
  • Iyo data inowanikwa yekupera-kwe-mwedzi yekushuma mukati mevhiki yekutanga yemwedzi unotevera, semuenzaniso.
• Kuvimbika
  • Iyo data ine chaiyo data mhando mudhatabhesi. Mavara ndiwo mavara, misi misi uye nhamba inhamba.
  • Mitemo iri mukati mezvinotarisirwa. Semuyenzaniso, nepo 212 madhigirii fahrenheit iri tembiricha chaiyo inogona kuyerwa, haisi kukosha kwakakodzera kune tembiricha yemunhu.  
  • Hunhu hune chimiro chakarurama. 1.000000 haina chirevo chakafanana ne1.
• Consistency
  • Iyo data inopindirana mukati
  • Iko hakuna maduplicate emarekodhi
• Kuvimbika
  • Hukama pakati pematafura hwakavimbika.
  • Haina kuchinjwa nemaune. Hunhu hunogona kurondwa kune kwazvakatangira. 
• Kukwana
  • Iko hakuna "maburi" mune data. Zvose zvezvinyorwa zvechinyorwa zvine hutsika.  
  • Iko hakuna NULL tsika.
• kunyatsoita
  • Dhata munzvimbo yekubika kana yekuongorora - iyo yekuchengetedza data, ingave pa-prem kana mugore - inoratidza masisitimu, kana masisitimu kana rekodhi.
  • Dhata rinobva kune zvinogoneka.

Isu tinobvumirana, saka, kuti dambudziko remhando yedata rakasakara sedata pacharo, dambudziko riripo uye rakakosha kugadzirisa. Saka, tinoita sei nezvazvo? Funga nezvechirongwa chako chemhando yedata sechirongwa chenguva refu, chisingapere.  

Hunhu hwe data hunonyatso miririra kuti chokwadi iyo data inomiririra sei chokwadi. Kutaura chokwadi, mamwe data akakosha kupfuura mamwe data. Ziva kuti ndeipi data yakakosha kune yakasimba bhizinesi sarudzo uye kubudirira kwesangano. Tanga ipapo. Tarisa pane iyo data.  

SeData Hunhu 101, chinyorwa ichi chisumo cheFreshman-chikamu chemusoro wenyaya: nhoroondo, zviitiko zvazvino, dambudziko, nei riri dambudziko uye nepamusoro-pamwero wekutarisa maitiro ekugadzirisa data mhando mukati mesangano. Tizivise kana iwe uchida kutarisa zvakadzama mune chero yeiyi misoro mune 200-level kana graduate-level chinyorwa. Kana zvakadaro, tichanyura zvakadzama mune izvo chaizvo mumwedzi iri kuuya.
