Cov ntaub ntawv rau Kev kawm
Los ntawm cov tsev kawm ntawv theem qis mus rau tsev kawm qib siab, kev kawm tsev kawm ntawv siv databases txhawm rau taug qab cov tub ntxhais kawm, qib, kev hloov pauv, cov ntawv sau thiab lwm cov ntaub ntawv tub ntxhais kawm. Muaj txawm tias tshwj xeeb database tej pob khoom npaj rau tsev kawm ntawv thiab tsev kawm qib siab.
Tib neeg kuj nug, cov ntaub ntawv siv hauv tsev kawm li cas?
tsev kawm ntawv siv a database khaws cov ntsiab lus hais txog lawv cov menyuam kawm ntawv, piv txwv li pes tsawg hnub lawv tau tawm mus tsev kawm ntawv mob. lub tsev kho mob yuav khaws cov ntsiab lus ntawm tag nrho nws cov neeg mob hauv a database , xws li keeb kwm ntawm lawv cov teeb meem kev noj qab haus huv. tsoom fwv siv a database khaws cov ntaub ntawv ntawm tib neeg cov nyiaj tau los them se.

- Lawv khaws cov ntaub ntawv tshwj xeeb siv los tswj cov ntaub ntawv.
- Lawv tuaj yeem daws cov teeb meem uas ntau tus neeg siv xav nkag mus (thiab tejzaum nws hloov) tib cov ntaub ntawv nkag.
Ntawm no, dab tsi yog ib qho kev kawm database?
Kev tshawb fawb Cov ntaub ntawv . Kev kawm Phau ntawv puv yog kev tshawb fawb database rau kev kawm cov tub ntxhais kawm, cov kws tshaj lij thiab cov neeg tsim cai. Nws suav nrog cov ntawv nyeem puv kev kawm phau ntawv journals uas npog qhov tseem ceeb ntawm kev kawm thiab lwm yam kev kawm, suav nrog kev pab them nqi tshwj xeeb kev kawm.
