Dab tsi yog SAS ETL ? SAS muab cov ntaub ntawv Management platform uas muaj ntau tshaj nees nkaum cov cuab yeej los ntawm ntau yam SAS Kev koom ua ke cov ntaub ntawv, Cov ntaub ntawv zoo, thiab cov khoom lag luam Master Data Management. Kev them nyiaj yug rau extract, transform thiab load ( ETL ) thiab rho tawm, thauj khoom thiab hloov pauv (ELT) cov kav dej.
Xav txog qhov no, ETL cov cuab yeej muaj dab tsi?

Tsis tas li ntawd, puas yog SAS lub tsev khaws ntaub ntawv? SAS System tau tsim nyob rau hauv 1970s thiab txij thaum ntawd los nws cov khoom ua nyob rau hauv cov ntaub ntawv warehouse , kev lag luam tsom xam thiab analytical txawj ntse. SAS (Statistical Analysis System) yog qhov tseeb tag nrho-hauv-ib cov ntaub ntawv uas ua rau nws yog qhov zoo tshaj plaws ntawm txhua tus neeg muag khoom. Nws tswj cov ntaub ntawv thiab hu cov txheej txheem.
Ntawm no, ETL software yog dab tsi?
Extract, Hloov, Load ( ETL ) yog txheej txheem hauv cov ntaub ntawv khaws cia. ETL Software pab nyob rau hauv cov ntaub ntawv rho tawm, cov ntaub ntawv hloov pauv thiab cov ntaub ntawv Loading. Cov software yog siv los muab cov ntaub ntawv los ntawm ntau qhov chaw rau hauv ib qho kev daws teeb meem.
ETL yog dab tsi thiab vim li cas nws tseem ceeb?
