Kev sim yog cov txheej txheem tshawb nrhiav uas tau ua los xyuas qhov zoo ntawm cov khoom. Cov ntaub ntawv - Kev kuaj Centric : Cov ntaub ntawv - kev ntsuam xyuas centric kiv puag ncig kuaj zoo ntawm cov cov ntaub ntawv . Lub hom phiaj ntawm cov cov ntaub ntawv - kev ntsuam xyuas centric yog los xyuas kom meej thiab raug cov ntaub ntawv yog nyob rau hauv qhov system.

Tom qab ntawd, data centric txhais li cas?

Cov ntaub ntawv centric hais txog ib qho architecture qhov twg cov ntaub ntawv yog cov khoom tseem ceeb thiab ruaj khov, thiab cov ntawv thov tuaj thiab mus. Hauv cov ntaub ntawv centric architecture, ua cov ntaub ntawv qauv ua ntej qhov kev siv ntawm ib daim ntawv thov thiab yuav nyob ib puag ncig thiab siv tau ntev tom qab nws ploj mus.

Ib yam li ntawd, cov ntaub ntawv xeem yog dab tsi hauv kev sim software? Cov ntaub ntawv xeem yog cov ntaub ntawv uas tau raug txheeb xyuas tshwj xeeb rau kev siv hauv kuaj , feem ntau ntawm ib lub computer program. Ib txhia cov ntaub ntawv tej zaum yuav raug siv nyob rau hauv ib txoj kev lees paub, feem ntau los xyuas kom meej tias cov txheej txheem muab tswv yim rau ib qho kev ua haujlwm ua rau qee qhov kev xav tau.

Ntxiv rau qhov no, ETL Testing txhais li cas?

Kev xeem ETL yog ua los xyuas kom meej tias cov ntaub ntawv uas tau raug thauj los ntawm ib qhov chaw mus rau qhov chaw tom qab kev hloov pauv kev lag luam yog qhov tseeb. Nws kuj suav nrog kev txheeb xyuas cov ntaub ntawv ntawm ntau theem nruab nrab uas tau siv los ntawm qhov chaw thiab qhov chaw. ETL stands rau Extract-Transform-Load.

Dab tsi yog cov txuj ci uas xav tau rau Kev Xeem ETL?
