A SAS data set yog ib pab pawg cov ntaub ntawv nqi ntawd SAS tsim thiab txheej txheem. A cov ntaub ntawv teev muaj. ib lub rooj nrog cov ntaub ntawv , npe. kev soj ntsuam, teeb tsa hauv kab. variables, koom nyob rau hauv kab.
Ib yam li ntawd, SAS cov ntaub ntawv kauj ruam yog dab tsi?
Cov DATA kauj ruam muaj ib pawg ntawm SAS nqe lus uas pib nrog a DATA nqe lus. Cov DATA nqe lus pib txheej txheem ntawm kev tsim a SAS data set thiab npe cov ntaub ntawv teeb. Cov nqe lus uas ua rau cov DATA kauj ruam tau muab tso ua ke, thiab cov syntax raug kuaj xyuas. Yog hais tias cov syntax yog lawm, ces cov nqe lus raug muab tua.
Ib yam li ntawd, kuv yuav tsim cov ntaub ntawv SAS li cas? Piv txwv 1: Kev Nyeem Ntawv Sab Nraud Cov ntaub ntawv Cheebtsam ntawm a DATA kauj ruam uas tsim ib SAS data teem los ntawm raw cov ntaub ntawv khaws cia rau hauv ib qho chaw sab nraud ntaub ntawv tau piav qhia ntawm no. Pib lub DATA kauj ruam thiab tsim cov ntaub ntawv SAS teev npe WEIGHT. Qhia rau sab nraud ntaub ntawv uas muaj koj cov ntaub ntawv . Nyeem ib cov ntaub ntawv thiab muab qhov tseem ceeb rau peb qhov sib txawv.
Ib yam li ntawd, SAS cov ntaub ntawv yog dab tsi?
SAS yog a ntaub ntawv Extension rau ASCII ntaub ntawv siv nrog Statistical Analysis Software. SAS sawv cev rau Statistical Analysis Software. SAS cov ntaub ntawv muaj cov lej code rau ib qho kev pab cuam lossis sub-program siv rau cov qauv ntaub ntawv thiab kev tshuaj xyuas. SAS Cov ntaub ntawv tuaj yeem qhib los ntawm Kev Tshawb Fawb Txog Kev Tshawb Fawb Software.
Dab tsi yog SET nqe lus hauv SAS?
Taw qhia. Kev ua haujlwm ntawm lub SET nqe lus yog ua cov uas twb muaj lawm SAS cov ntaub ntawv teeb raws li kev nkag mus rau DATA kauj ruam. Nrog tsis muaj kev xaiv tau teev tseg, lub SAS System ua raws li txhua qhov kev soj ntsuam hauv cov ntaub ntawv muaj npe teeb , ib qho kev soj ntsuam ntawm ib lub sij hawm, kom txog rau thaum tsis muaj kev soj ntsuam ntxiv mus rau txheej txheem.

Cov ntaub ntawv hom thiab cov qauv ntaub ntawv yog dab tsi?
Cov qauv ntaub ntawv yog ib txoj hauv kev piav qhia txog ib txoj hauv kev los npaj cov ntaub ntawv kom ua haujlwm andalogrithms tuaj yeem siv tau yooj yim dua. Ib hom ntaub ntawv piav qhia txog cov ntaub ntawv uas txhua tus sib koom ua ke. Piv txwv li tus lej cov ntaub ntawv hom piav qhia txhua tus lej uas lub khoos phis tawj tuaj yeem ua tau
Dab tsi yog qhov txawv ntawm XML cov ntaub ntawv thiab cov ntaub ntawv sib txheeb?
Qhov sib txawv loj ntawm XML cov ntaub ntawv thiab cov ntaub ntawv sib txheeb Ib daim ntawv XML muaj cov ntaub ntawv hais txog kev sib raug zoo ntawm cov ntaub ntawv rau ib leeg nyob rau hauv daim ntawv ntawm hierarchy. Nrog rau tus qauv kev sib raug zoo, tib hom kev sib raug zoo uas tuaj yeem txhais tau yog cov lus niam txiv thiab cov rooj sib raug zoo
Dab tsi yog qhov sib txawv ntawm pab pawg cov ntaub ntawv thiab cov ntaub ntawv tsis yog pawg?
Ob leeg yog cov ntaub ntawv muaj txiaj ntsig ntawm cov ntaub ntawv tab sis qhov sib txawv ntawm lawv yog cov ntaub ntawv tsis muaj ntaub ntawv yog rawdata. Qhov no txhais tau hais tias nws nyuam qhuav tau sau tab sis tsis txheeb rau hauv ib pawg lossis cov chav kawm. Ntawm qhov tod tes, groupeddata yog cov ntaub ntawv uas tau teeb tsa ua pawg los ntawm cov ntaub ntawv nyoos
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
Dab tsi yog cov teeb meem ntawm kev tswj cov ntaub ntawv hauv cov ntaub ntawv ib txwm muaj?
Nyob rau tib lub sijhawm, qhov kev tswj hwm cov ntaub ntawv ib puag ncig tsim teeb meem xws li cov ntaub ntawv rov ua dua thiab tsis sib xws, cov kev pab cuam-cov ntaub ntawv dependence, inflexibility, tsis muaj kev ruaj ntseg, thiab tsis muaj cov ntaub ntawv sib qhia thiab muaj
