The DIKW pyramid , kuj paub ntau yam xws li DIKW hierarchy, kev txawj ntse hierarchy, kev paub hierarchy, cov ntaub ntawv hierarchy, thiab cov cov ntaub ntawv pyramid , hais txog xoob mus rau ib chav kawm ntawm cov qauv rau sawv cev rau cov qauv tsim thiab / lossis kev sib raug zoo ntawm cov ntaub ntawv , ntaub ntawv, kev txawj ntse, thiab kev txawj ntse.
Ntxiv mus, DIKW qauv ua haujlwm li cas?
Cov DIKW (Data, Information, Knowledge, Wisdom) qauv qhia tau hais tias tib neeg lub siab tuaj yeem txav cov ntaub ntawv nyoos mus rau cov dav hlau siab dua los ntawm kev txhim kho lub koom haum. Kev sib raug zoo ntawm cov ntaub ntawv cov ntsiab lus ua rau cov khoom thiab bytes kom tau txais lub ntsiab lus thiab yog li ua cov ntaub ntawv rau peb.
Ib yam li ntawd, vim li cas DIKW tseem ceeb? DIKW Model yog ib qhov tseem ceeb ib feem ntawm ITIL Knowledge Management nyob rau hauv Kev Pabcuam Hloov Hloov Module. Nws yog cov duab sawv cev ntawm kev paub yuav ua li cas thiaj li koom tau hauv lub koom haum. Peb paub tias, thaum peb sau cov ntaub ntawv nyoos, nws tuaj rau hauv daim ntawv jumbled.
Dhau li, qhov twg los thawj cov ntaub ntawv lossis cov ntaub ntawv?
Zoo li lwm cov qauv hierarchy, Kev Paub Pyramid tau nruj tsim cov tsev thaiv - cov ntaub ntawv los ua ntej , cov ntaub ntawv yog tom ntej no, ces kev paub raws li thiab thaum kawg kev txawj ntse yog nyob rau sab saum toj. Hauv lwm lo lus, qhov ntau peb txhawb peb cov ntaub ntawv nrog lub ntsiab lus thiab cov ntsiab lus, qhov kev paub ntau dua thiab kev pom peb tau tawm ntawm nws.
Yuav ua li cas cov ntaub ntawv dhau los ua kev paub thiab thaum kawg kev txawj ntse?
Cov ntaub ntawv analytics ua rau kev nkag siab ntawm txhua qhov no cov ntaub ntawv thiab tsim cov ntaub ntawv los ntawm nws. Raws li cov ntaub ntawv no, koj tuaj yeem txiav txim siab thiab nqis tes ua. Cov cov ntaub ntawv -cov ntaub ntawv- kev paub - kev txawj ntse (DIKW) qauv yog qhov tseem ceeb rau kev nkag siab tias raw li cas cov ntaub ntawv hloov mus rau hauv cov ntaub ntawv tseem ceeb, thiab tom qab ntawd mus rau hauv kev paub, thiab thaum kawg kev txawj ntse.

Cov ntaub ntawv hom thiab cov qauv ntaub ntawv yog dab tsi?
Cov qauv ntaub ntawv yog ib txoj hauv kev piav qhia txog ib txoj hauv kev los npaj cov ntaub ntawv kom ua haujlwm andalogrithms tuaj yeem siv tau yooj yim dua. Ib hom ntaub ntawv piav qhia txog cov ntaub ntawv uas txhua tus sib koom ua ke. Piv txwv li tus lej cov ntaub ntawv hom piav qhia txhua tus lej uas lub khoos phis tawj tuaj yeem ua tau
Dab tsi yog qhov txawv ntawm XML cov ntaub ntawv thiab cov ntaub ntawv sib txheeb?
Qhov sib txawv loj ntawm XML cov ntaub ntawv thiab cov ntaub ntawv sib txheeb Ib daim ntawv XML muaj cov ntaub ntawv hais txog kev sib raug zoo ntawm cov ntaub ntawv rau ib leeg nyob rau hauv daim ntawv ntawm hierarchy. Nrog rau tus qauv kev sib raug zoo, tib hom kev sib raug zoo uas tuaj yeem txhais tau yog cov lus niam txiv thiab cov rooj sib raug zoo
Dab tsi yog qhov sib txawv ntawm pab pawg cov ntaub ntawv thiab cov ntaub ntawv tsis yog pawg?
Ob leeg yog cov ntaub ntawv muaj txiaj ntsig ntawm cov ntaub ntawv tab sis qhov sib txawv ntawm lawv yog cov ntaub ntawv tsis muaj ntaub ntawv yog rawdata. Qhov no txhais tau hais tias nws nyuam qhuav tau sau tab sis tsis txheeb rau hauv ib pawg lossis cov chav kawm. Ntawm qhov tod tes, groupeddata yog cov ntaub ntawv uas tau teeb tsa ua pawg los ntawm cov ntaub ntawv nyoos
Vim li cas kem taw qhia cov ntaub ntawv khaws cia ua cov ntaub ntawv nkag ntawm disks sai dua li kab qhia cov ntaub ntawv khaws cia?
Kem oriented databases (aka columnar databases) yog qhov tsim nyog rau kev ntsuas kev ua haujlwm ntau dua vim tias cov ntaub ntawv hom ntawv (kem hom) qiv nws tus kheej kom nrawm dua cov lus nug ua - scans, aggregation thiab lwm yam. Ntawm qhov tod tes, kab oriented databases khaws ib kab (thiab tag nrho nws. kab) contiguously
Dab tsi yog cov teeb meem ntawm kev tswj cov ntaub ntawv hauv cov ntaub ntawv ib txwm muaj?
Nyob rau tib lub sijhawm, qhov kev tswj hwm cov ntaub ntawv ib puag ncig tsim teeb meem xws li cov ntaub ntawv rov ua dua thiab tsis sib xws, cov kev pab cuam-cov ntaub ntawv dependence, inflexibility, tsis muaj kev ruaj ntseg, thiab tsis muaj cov ntaub ntawv sib qhia thiab muaj
