Cov Data Management Cycle . Hais dav dav, muaj peb thaj chaw ntawm kev tswj cov ntaub ntawv : Sau - Nrhiav kev cia siab tshiab, kev muag khoom muag. Active Kev tswj hwm - tshuaj xyuas thiab hloov kho cov ntaub ntawv kom paub meej nws qhov tseeb.
Hais txog qhov no, dab tsi yog kev tswj xyuas lub neej voj voog?
Kev tswj cov ntaub ntawv lub neej voj voog (DLM) yog txoj hauv kev raws li txoj cai los tswj kev khiav ntawm cov ntaub ntawv xov xwm cov ntaub ntawv thoob plaws nws lub neej voj voog : los ntawm kev tsim thiab pib cia rau lub sijhawm thaum nws dhau los lawm thiab raug tshem tawm.
Tom qab ntawd, lo lus nug yog, dab tsi yog lub voj voog cov ntaub ntawv? Cov Cov ntaub ntawv Kev ua haujlwm Lub voj voog yog ib tug series ntawm cov kauj ruam ua los extract cov ntaub ntawv tseem ceeb los ntawm raw cov ntaub ntawv . Txawm hais tias txhua kauj ruam yuav tsum tau ua kom tiav, qhov kev txiav txim yog cyclic. Qhov tso zis thiab cia theem tuaj yeem ua rau rov ua dua ntawm qhov cov ntaub ntawv sau theem, ua rau lwm tus lub voj voog ntawm cov ntaub ntawv ua.
Raws li, kev tswj cov ntaub ntawv piav qhia yog dab tsi?
Kev tswj cov ntaub ntawv yog tus txheej txheem tswj xyuas uas suav nrog kev tau txais, lees paub, khaws cia, tiv thaiv, thiab ua tiav yuav tsum tau ua cov ntaub ntawv los xyuas kom meej lub accessibility, kev cia siab, thiab timeliness ntawm lub cov ntaub ntawv rau nws cov neeg siv. Kev tswj cov ntaub ntawv software yog qhov tseem ceeb, raws li peb tab tom tsim thiab siv cov ntaub ntawv ntawm tus nqi uas tsis tau pom dua.
