Ib yam li ib tug yuav nug, dab tsi yog lub tswv yim kev lag luam cov ntaub ntawv qauv?
Enterprise Conceptual Model ECM yog qib siab cov ntaub ntawv qauv nrog qhov nruab nrab ntawm 10-12 lub tswv yim rau ib cheeb tsam. Cov tswv yim qhia txog kev lag luam ntau dua li cov ncauj lus. ECM yog suav nrog cov ntsiab lus, lawv txhais thiab lawv cov kev sib raug zoo.
Mercy tuaj yeem tau txais txiaj ntsig zoo li cas los ntawm kev lag luam cov ntaub ntawv qauv? Kev hlub tshua muab txiaj ntsig los ntawm Enterprise cov ntaub ntawv qauv los ntawm kev muaj qhov system kom meej thiab loj dua database . Loj cov ntaub ntawv muab lub platform hloov tau los khaws thiab khaws cov cov ntaub ntawv
Ib qho tseem yuav nug, dab tsi tuaj yeem ua tau raws li kev lag luam cov ntaub ntawv qauv hauv kev lag luam?
Ib ua lag luam qauv , uas yog suav nrog ib lossis ntau qhov kev kawm qauv , yog siv los sau cov txheej txheem thiab cov ntaub ntawv rau ib lub koom haum, kev lag luam los yog kev lag luam . Qhov kev sib koom ua ke no yog qhov tseem ceeb yog tias ib lub koom haum yuav tsum paub txog cov txiaj ntsig ntawm kev tsim khoom ntau ntxiv thiab txo cov kev tsim kho thiab kev saib xyuas cov nqi.
Enterprise data architecture yog dab tsi?
Enterprise cov ntaub ntawv architecture (EDA) yog hais txog ib qho kev sau los ntawm cov qauv tsim qauv tsim los ua kom haum rau IT cov kev pabcuam thiab cov ntaub ntawv muaj txiaj ntsig nrog kev lag luam zoo. EDA yog siv los coj kev sib koom ua ke, txhim kho kom zoo thiab ua tiav cov ntaub ntawv kev xa khoom.

Lub tshuab luam ntawv twg luam tawm cov cim thiab cov cim thiab Tsis tuaj yeem luam tawm cov duab?
Daisy log tshuab luam ntawv luam tawm tsuas yog cov cim thiab cov cim thiab tsis tuaj yeem luam tawm cov duab
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
Kuv yuav ua li cas los ua ib tus kws tsim khoom lag luam cov ntaub ntawv?
Txhawm rau mus nrhiav haujlwm ua tus kws tsim khoom lag luam cov ntaub ntawv, koj xav tau bachelor's degree hauv computer science, informationtechnology (IT), lossis computer engineering, nrog rau ntau xyoo ntawm kev ua haujlwm nrog kev tswj cov ntaub ntawv lossis softwarearchitecture
