Data mining vs Data Warehousing

Data Mining thiab Data Warehousing yog ob qho tib si muaj zog thiab nrov tshaj plaws rau kev tshuaj xyuas cov ntaub ntawv. Cov neeg siv uas nyiam mus rau kev txheeb cais siv Data Mining. Lawv siv cov qauv kev txheeb cais los nrhiav cov qauv zais hauv cov ntaub ntawv. Cov ntaub ntawv miners txaus siab nrhiav kev sib raug zoo ntawm cov ntaub ntawv sib txawv, uas yog qhov muaj txiaj ntsig zoo rau kev lag luam. Tab sis ntawm qhov tod tes, cov kws tshaj lij cov ntaub ntawv uas tuaj yeem txheeb xyuas qhov ntev ntawm kev lag luam ncaj qha yuav siv cov ntaub ntawv warehouses.

Data mining tseem hu ua Knowledge Discovery in data (KDD). Raws li tau hais los saum no, nws yog thaj chaw ntawm kev tshawb fawb hauv computer, uas cuam tshuam nrog kev rho tawm cov ntaub ntawv yav dhau los tsis paub thiab nthuav tawm los ntawm cov ntaub ntawv nyoos. Vim qhov kev loj hlob ntawm cov ntaub ntawv, tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam xws li kev lag luam, cov ntaub ntawv mining tau dhau los ua cov cuab yeej tseem ceeb heev los hloov cov ntaub ntawv loj no rau hauv kev lag luam txawj ntse, vim tias phau ntawv rho tawm ntawm cov qauv tau dhau los ua tsis yooj yim rau ob peb lub xyoo dhau los. Piv txwv li, tam sim no nws tau raug siv rau ntau yam kev siv xws li kev txheeb xyuas kev sib raug zoo, kev dag ntxias thiab kev lag luam. Cov ntaub ntawv mining feem ntau cuam tshuam nrog plaub yam haujlwm hauv qab no: kev sib koom ua ke, kev faib tawm, kev rov qab los, thiab kev koom ua ke. Clustering yog txheeb xyuas cov pab pawg zoo sib xws los ntawm cov ntaub ntawv tsis tsim nyog. Kev faib tawm yog kev kawm cov cai uas tuaj yeem siv rau cov ntaub ntawv tshiab thiab feem ntau yuav suav nrog cov kauj ruam hauv qab no: ua ntej ntawm cov ntaub ntawv, tsim qauv, kev kawm / kev xaiv thiab kev ntsuam xyuas / validation. Regression yog nrhiav kev ua haujlwm nrog qhov yuam kev tsawg heev rau cov qauv ntaub ntawv. Thiab lub koom haum tab tom nrhiav kev sib raug zoo ntawm kev sib txawv. Cov ntaub ntawv mining feem ntau yog siv los teb cov lus nug xws li dab tsi yog cov khoom tseem ceeb uas yuav pab kom tau txais txiaj ntsig siab xyoo tom ntej hauv Wal-Mart?

Raws li tau hais los saum no, Cov ntaub ntawv khaws cia kuj tseem siv rau kev tshuaj xyuas cov ntaub ntawv, tab sis los ntawm cov neeg siv sib txawv thiab lub hom phiaj sib txawv me ntsis hauv siab. Piv txwv li, thaum nws los txog rau cov khw muag khoom lag luam, Cov ntaub ntawv khaws cia cov neeg siv tau txhawj xeeb ntau dua li cov kev yuav khoom uas nrov ntawm cov neeg siv khoom, yog li cov txiaj ntsig ntawm kev txheeb xyuas tuaj yeem pab cov neeg siv khoom los ntawm kev txhim kho cov neeg siv khoom. Tab sis cov ntaub ntawv miners ua ntej xav txog qhov kev xav xws li cov neeg siv khoom yuav ib yam khoom thiab tshuaj xyuas cov ntaub ntawv los ntsuas qhov kev xav. Cov ntaub ntawv khaws cia tuaj yeem ua tau los ntawm cov khw muag khoom loj uas pib khaws nws cov khw muag khoom nrog tib qhov ntau thiab tsawg ntawm cov khoom tom qab pom tias New York cov khw muag cov khoom muag me me sai dua hauv cov khw muag khoom Chicago. Yog li, los ntawm kev saib qhov tshwm sim no tus neeg muag khoom tuaj yeem khaws lub khw New York nrog qhov me me piv rau cov khw muag khoom Chicago.

Yog li, raws li koj tuaj yeem pom meej, ob hom kev tshuaj ntsuam no tshwm sim zoo ib yam li qhov muag liab qab. Ob leeg txhawj xeeb txog kev nce nyiaj tau los raws li cov ntaub ntawv keeb kwm. Tab sis tau kawg, muaj qhov sib txawv tseem ceeb. Hauv cov ntsiab lus yooj yim, Cov Ntaub Ntawv Mining thiab Cov Ntaub Ntawv Warehousing tau mob siab rau muab ntau hom kev tshuaj ntsuam xyuas, tab sis twv yuav raug hu rau ntau hom neeg siv. Hauv lwm lo lus, Cov Ntaub Ntawv Mining nrhiav kev sib raug zoo, patters los txhawb kev txheeb xyuas qhov kev xav. Tab sis, Data Warehousing teb cov lus nug dav dua thiab nws hlais thiab txiav cov ntaub ntawv los ntawm qhov ntawd mus kom paub txog txoj hauv kev txhim kho yav tom ntej.
