Njengoba kunikezwe lombhalo wenkomba, izitolo zamakholomu zisetshenziselwa ini?
Context:I-column-oriented DBMS noma i-columnar DBMS uhlelo lokuphathwa kwedatha (i-DBMS) eligcina amatafula wedatha ngekholomu kunemigqa. Izinzuzo zihlanganisa ukufinyelela kwedatha ngendlela ephumelelayo uma ubuza kuphela iqoqo elincane lamakholomu (ngokususa isidingo sokufunda amakholomu angabalulekile), kanye nezinketho eziningi zokucindezela idatha. Nokho, ngokuvamile aziphumeleli kangako ekufakeni imininingwane emisha.  Ukusetshenziswa okusebenzayo kwesitolo sekholomu kuqhathaniswa nesitolo somugqa kuhluke kancane emhlabeni we-DBMS yobudlelwano. Zombili izinqolobane zedatha ezinamakholomu nemigqa zingasebenzisa izilimi zendabuko zokubuza idatha njenge-SQL ukulayisha idatha nokwenza imibuzo. Zombili imigqa kanye columnar yolwazi bangaba umgogodla ohlelweni ukukhonza idatha for extract ezivamile, ukuguqula, ukulayisha (ETL) namathuluzi.
I-column store database igcina idatha njenganoma iyiphi enye indlela yokuphatha i-database. Imininingwane ngokwayo igcinwa ngokulandelana ukuze kuthuthukiswe ukusebenza kwe-scan kusethi engaphansi kwamakholomu ngamanye.
