Dab tsi yog Qhov Kev Ntsuam Xyuas Ntaub Ntawv?
Cov ntaub ntawv analytics yog lub npe dav dav rau ntau hom kev txheeb xyuas cov ntaub ntawv. Nws cuam tshuam nrog kev siv cov kev nkag siab thiab cov ncauj lus kom ntxaws los daws qhov teeb meem tshwj xeeb. Hauv cov ntsiab lus yooj yim, kev txheeb xyuas cov ntaub ntawv cuam tshuam nrog kev txheeb xyuas cov ntaub ntawv lossis kev txheeb cais.
Raws li kev nkag siab thiab kev siv cov qauv ntawm cov ntaub ntawv, cov ntaub ntawv analytics yog mus txog qhov kawg uas kev txiav txim siab muaj txiaj ntsig zoo. Kev tshawb fawb hauv kev nkag siab tias cov ntaub ntawv yuav tsum tau ua ntau theem thiab cov txheej txheem ua ntej yuav txiav txim siab.
Txhua hom ntaub ntawv tuaj yeem raug rau cov ntaub ntawv txheeb xyuas raws li nws yog qhov zais cia rau kev ua tau zoo, kev ua kom tau nyiaj ntau tshaj, thiab kev txiav txim siab raug hauv txhua lub lag luam.
Lwm qhov zoo nkauj ntawm cov ntaub ntawv txheeb xyuas yog nws txoj haujlwm ntau haiv neeg. Nrog cov ntaub ntawv txheeb xyuas, koj tuaj yeem ua tus kws tshuaj ntsuam xyuas cov ntaub ntawv, tus kws tshuaj ntsuam xyuas kev lag luam, tus kws tshawb fawb cov ntaub ntawv, cov ntaub ntawv engineer, tus kws tshuaj ntsuam xyuas kev ua haujlwm, tus thawj tswj hwm qhov project, lossis IT systems analytics, los hais tab sis ob peb.
