Txoj kev xaiv nkag siab txo cov ntaub ntawv cached thaum lub sijhawm sib tham thiab txhim kho kev ua haujlwm. Siv qhov kev xaiv no nrog rau Qhov Chaw Qualifier Number of Sorted Ports xaiv lossis Sorter hloov pauv kom dhau cov ntaub ntawv txheeb xyuas mus rau Aggregator transformation.
txhais tau li cas los ntawm kev txheeb cov tswv yim hauv kev sib sau ua ke?
Nyob rau hauv daim ntawv qhia uas siv 'Sorted Input' kev xaiv, tus Informatica server xav tias tag nrho cov ntaub ntawv nkag mus rau hauv ib qho kev hloov pauv tau raug txheeb xyuas rau hauv cov pab pawg uas sib haum rau cov neeg sib sau ua ke 'Pab Los Ntawm' chaw nres nkojVim li ntawd, tus neeg rau zaub mov tsis tas yuav nyeem tag nrho cov ntaub ntawv ua ntej ua kev suav.
Dab tsi yog qhov sib txawv ntawm kev sib sau ua haujlwm nrog cov tswv yim txheeb xyuas thiab tsis muaj cov lus txheeb cais?
Kev txhim kho kev ua tau zoo uas siv cov tswv yim txheeb xyuas yog qhov tseem ceeb dua thaum koj tau teeb tsa qhov kev sib kho nrog ntau qhov sib faib. Tsis tas li, txheeb cov tswv yim tsis tuaj yeemsiv tau, thaum koj tau nested aggregate muaj nuj nqi nyob rau hauv lub aggregator los yog kev sib kho siv incremental aggregation.
Yuav ua li cas yog tias qhov kev xaiv nkag tau raug xaiv hauv qhov kev hloov pauv hloov pauv tab sis daim ntawv hla dhau thiab txheeb cov tswv yim rau kev sib sau?
4. Txheeb cov tswv yim rau kev hloov pauv sib sau ua ke yuav txhim kho kev ua haujlwm ntawm daim ntawv qhia. Txawm li cas los xij, yog tias cov tswv yim txheeb cais tau siv rau cov lus qhia sib sau ua ke lossis kev sib sau ua ke, ces daim ntawv qhia yuav ua rau kev sib tham tsis ua haujlwm.
Nyob rau hauv qhov xwm txheej twg xaiv xaiv cov tswv yim hauv kev sib sau yuav ua tsis tau qhov kev sib kho?
Nyob rau hauv qhov xwm txheej twg xaiv Xaiv Cov Lus Qhia nyob rau hauv aggregator yuav ua tsis tau qhov kev sib kho? Yog tias cov ntaub ntawv tawm tswv yim tsis raug txheeb xyuas kom raug, kev sib kho yuav ua tsis tiav Tsis tas li yog tias cov ntaub ntawv nkag tau raug txheeb xyuas kom raug, qhov kev sib kho yuav ua tsis tiav yog tias kev txheeb xyuas los ntawm cov chaw nres nkoj thiab pab pawg los ntawm cov chaw nres nkoj ntawm cov khoom sib sau. tsis nyob rau hauv tib txoj kev.
