OLAP (Online Analytical Processing) yog qhov tshuab tom qab ntau daim ntawv thov Kev Txawj Ntse (BI). OLAP yog tus muaj zog tshuab rau kev tshawb pom cov ntaub ntawv, suav nrog kev muaj peev xwm rau kev saib daim ntawv ceeb toom tsis pub dhau, kev txheeb xyuas nyuaj, thiab kwv yees "dab tsi yog" qhov xwm txheej (pob nyiaj, kev kwv yees) kev npaj.
Ib yam li ntawd, nws raug nug, OLAP piv txwv yog dab tsi?
OLAP Cube txhais. Ib OLAP Lub voos xwmfab yog cov qauv ntaub ntawv uas tso cai rau kev soj ntsuam ceev ntawm cov ntaub ntawv raws li ntau qhov Dimensions uas txhais cov teeb meem kev lag luam. Lub voos xwmfab multidimensional rau kev tshaj tawm kev muag khoom yuav yog, rau piv txwv , muaj li ntawm 7 Dimensions: Tus Neeg Muag Khoom, Tus Nqi Muag Khoom, Thaj Chaw, Khoom Muag, Thaj Chaw, Lub Hlis, Xyoo.
Kuj Paub, OLAP yog dab tsi thiab nws hom? OLAP yog ib lub tshuab uas tso cai rau cov kws tshuaj ntsuam kom rho tawm thiab saib cov ntaub ntawv ua lag luam los ntawm cov ntsiab lus sib txawv. Muaj thawj tsib hom ntawm kev ua haujlwm analytical hauv OLAP 1) Npog-up 2) Drill-down 3) Slice 4) tsuav thiab 5) Pivot. Peb hom ntawm dav siv OLAP systems yog MOLAP, ROLAP, thiab Hybrid OLAP.
Ib yam li ib tug yuav nug, OLAP lub hom phiaj yog dab tsi?
OLAP (online analytical processing) yog ib txoj hauv kev suav uas ua rau cov neeg siv tau yooj yim thiab xaiv rho tawm thiab nug cov ntaub ntawv txhawm rau txheeb xyuas nws los ntawm cov ntsiab lus sib txawv.
OLAP qauv yog dab tsi?
Online Analytical Processing Server ( OLAP ) yog raws li cov ntaub ntawv multidimensional qauv . Nws tso cai rau cov thawj coj, thiab cov kws tshuaj ntsuam kom tau txais kev nkag siab ntawm cov ntaub ntawv los ntawm kev ceev, zoo ib yam, thiab sib tham sib nkag mus rau cov ntaub ntawv.

Lub luag haujlwm ntawm computer cov ntaub ntawv technology yog dab tsi?
Computer Information Technology (CIT) yog siv thiab kawm txog computers, networks, computer languages, thiab databases hauv ib lub koom haum los daws cov teeb meem tiag tiag. Qhov loj npaj cov tub ntxhais kawm rau kev siv programming, networking, kev tswj hwm, thiab kev txhim kho hauv internet
Dab tsi yog embedded technology?
Lub kaw lus embedded yog lub khoos phis tawj nrog kev ua haujlwm tshwj xeeb hauv lub tshuab hluav taws xob lossis hluav taws xob loj dua, feem ntau nrog cov kev txwv ntawm lub sijhawm. Nws yog embeddedas ib feem ntawm ib tug ua tiav ntaus ntawv feem ntau suav nrog hardware thiab mechanical qhov chaw. Embedded systems tswj ntau yam khoom siv tsis siv niaj hnub no
Dab tsi yog qhov tseeb technology hauv kev siv technology?
Artificial txawj ntse. Blockchain. Augmented Reality thiab Virtual Reality. Cloud Computing
Dab tsi yog mashups hauv technology?
Lub mash-up (qee zaum sau ua ib lo lus, mashup) yog nplooj ntawv Web lossis daim ntawv thov uas sib koom ua ke los ntawm ob lossis ntau qhov chaw. Kev lag luam mash-up feem ntau ua ke nrog cov ntaub ntawv hauv tuam txhab thiab cov ntawv thov nrog cov ntaub ntawv sab nraud, SaaS (software ua ib qho kev pabcuam) thiab cov ntsiab lus hauv Web
Dab tsi yog industrial automation technology?
Kev lag luam automation yog siv cov kev tswj hwm, xws li khoos phis tawj lossis cov neeg hlau, thiab cov ntaub ntawv thev naus laus zis los tuav cov txheej txheem sib txawv thiab cov tshuab hauv kev lag luam los hloov tib neeg. Nws yog lub kauj ruam thib ob dhau ntawm kev siv tshuab hauv kev lag luam
