Cov kauj ruam rau nthuav qhia thiab tsom xam cov ntaub ntawv :
Teeb lub hom phiaj ntawm kev kawm thiab ua ib daim ntawv teev npe cov ntaub ntawv yuav tsum tau sau thiab nws hom. Sau / tau cov ntaub ntawv los ntawm qhov chaw pib lossis theem nrab. Hloov hom ntawv ntawm cov ntaub ntawv , i.e., rooj, maps, graphs, thiab lwm yam nyob rau hauv hom xav tau.
Tsis tas li ntawd, koj sau cov ntaub ntawv nthuav qhia li cas?
Kev nthuav qhia cov txiaj ntsig
- Tsom ntsoov rau tsab xov xwm ntawm qhov sib txawv tseem ceeb thiab cov ncauj lus.
- Npaj cov tswv yim hauv qhov kev txiav txim siab thiab nyob rau hauv kev txiav txim ntawm qhov tseeb lossis qhov tseem ceeb.
- Khaws cov lus kom yooj yim raws li qhov kev kawm tso cai.
- Siv cov duab ntxiv rau cov ntawv nyeem thiab cov rooj sib txuas lus.
Ib yam li ntawd, koj sau cov kev tshawb pom hauv daim ntawv tshawb fawb li cas? Cov Cov txiaj ntsig ntu yuav tsum suav nrog kev tshawb pom ntawm koj kawm thiab tsuas yog tus kev tshawb pom ntawm koj kawm . Cov kev tshawb pom suav nrog: Cov ntaub ntawv nthuav tawm hauv cov lus, kab kos, kab kos, thiab lwm yam duab (tej zaum yuav muab tso rau hauv kev tshawb fawb ntawv los yog ib nplooj ntawv cais) Ib qho kev tsom xam ntawm cov ntaub ntawv no piav qhia nws lub ntsiab lus hauv kab lus.
Cov lus nug tseem yog, dab tsi yuav tsum suav nrog hauv kev nthuav qhia kev tshawb fawb?
Cov kev nthuav qhia yuav tsum suav nrog : Cov lus qhia luv luv, koj qhov kev xav, cov lus piav qhia luv luv ntawm cov txheej txheem, cov rooj thiab / lossis cov duab ntsig txog koj qhov kev tshawb pom, thiab kev txhais ntawm koj cov ntaub ntawv. Cov kev nthuav qhia yuav tsum tsis pub ntev tshaj 10 feeb. Qhov ntawd tsis yog sijhawm ntau. Npaj kom xav tau li 1 feeb rau ib daim swb.
Lub hom phiaj ntawm kev nthuav qhia cov ntaub ntawv yog dab tsi?
