Qhov sib txawv tseem ceeb ntawm DBMS thiab Cov Ntaub Ntawv Tswj Xyuas Cov Ntaub Ntawv yog tias DBMS khaws cov ntaub ntawv rau lub hard disk raws li tus qauv thaum lub kaw lus tswj cov ntaub ntawv khaws cov ntaub ntawv rau lub hard disk yam tsis siv cov qauv.
DBMS yog ib qho software tsim thiab tswj cov ntaub ntawv hauv kev sib koom ua ke thaum lub kaw lus tswj hwm cov ntaub ntawv yog software tswj cov ntaub ntawv hauv lub computer.
DBMS yog dab tsi?
DBMS sawv cev rau Database Management System thiab nws pab tsim thiab tswj cov ntaub ntawv, uas yog sau cov ntaub ntawv. Tsis tas li ntawd, DBMS khaws cov ntaub ntawv hauv cov ntxhuav. Ntawm no, ua ntej, tus neeg siv yuav tsum tsim cov qauv los khaws cov ntaub ntawv. Tom qab ntawd cov ntaub ntawv khaws cia yuav tshwm sim raws li cov qauv ntawd.
Ib qho txiaj ntsig loj ntawm DBMS vim tias cov qauv no yog nws muab cov lus nug. Nws yooj yim rau kev nkag mus, tshawb nrhiav, hloov kho thiab tshem tawm cov ntaub ntawv siv cov lus nug. Structured Query Language (SQL) yog hom lus los sau cov lus nug rau DBMS. DBMS tuav ib qho chaw khaws ntaub ntawv thiab ntau tus neeg siv nkag mus rau qhov chaw khaws cia ib leeg. Nws tseem tswj xyuas cov ntaub ntawv ncaj ncees los ntawm kev siv cov kev txwv. Ntxiv mus, nws txo cov ntaub ntawv redundancy thiab nce cov ntaub ntawv sib xws.
DBMS txhawb ntau tus neeg siv ib puag ncig. Yog li ntawd, ntau tus neeg siv tuaj yeem nkag mus rau cov ntaub ntawv tib lub sijhawm. Nws kuj tseem tuaj yeem ua kom ib cov ntaub ntawv muaj nyob rau ib chav haujlwm tsis muaj rau lwm qhov. Zuag qhia tag nrho, DBMS tsim nyog rau lub koom haum loj los tswj ntau cov ntaub ntawv.
Dab tsi yog Kev Tswj Xyuas Cov Ntaub Ntawv?
Ib txoj kev tswj cov ntaub ntawv tswj xyuas yuav ua li cas nyeem thiab sau cov ntaub ntawv rau lub hard disk. Thaum txhim kho lub operating system, cov ntaub ntawv kaw lus kuj nruab rau lub computer. Piv txwv li, OS xws li Linux thiab Windows muab cov ntaub ntawv kaw lus. Nws khaws cov ntaub ntawv rau lub hard disk thiab khaws cia thiab khaws cov ntaub ntawv tshwm sim los ntawm qhov kev tswj hwm cov ntaub ntawv no.
Hauv cov ntaub ntawv, txhua tus neeg siv siv cov ntaub ntawv raws li qhov yuav tsum tau ua. Piv txwv li, hauv chav muag khoom, ib tus neeg ua haujlwm yuav khaws cov ntsiab lus ntawm cov neeg ua haujlwm muag khoom, thiab lwm tus neeg ua haujlwm yuav khaws cov ntsiab lus ntawm cov nyiaj hli. Tib cov ntaub ntawv tej zaum yuav replicated. Yog li, yuav muaj cov ntaub ntawv redundancy. Thaum hloov kho cov ntaub ntawv, tus neeg siv yuav tsum kuaj xyuas txhua qhov chaw uas cov ntaub ntawv muaj. Tsis nco qab hloov qhov hloov tshiab tuaj yeem ua rau cov ntaub ntawv tsis sib xws. Qee zaum, nws yuav tsum tau khaws cov ntaub ntawv raws li cov xwm txheej. Kev siv cov kev txwv kuj nyuaj nrog kev tswj cov ntaub ntawv. Kev tswj cov ntaub ntawv yog qhov tsim nyog rau lub koom haum me los cuam tshuam nrog cov neeg siv tsawg.
Dab tsi yog qhov txawv ntawm DBMS thiab Kev Tswj Xyuas Cov Ntaub Ntawv?

| DBMS yog ib qho software tsim thiab tswj cov ntaub ntawv uas muab txoj hauv kev los tsim, khaws, hloov kho thiab tswj cov ntaub ntawv. | A cov ntaub ntawv tswj hwm yog software tswj cov ntaub ntawv hauv lub computer. |
| Data Redundancy | |
| Data redundancy tsawg hauv DBMS. | Hauv kev tswj cov ntaub ntawv, cov ntaub ntawv rov ua dua yog siab. |
| kev sib haum xeeb | |
| Hauv DBMS, cov ntaub ntawv sib xws yog siab. | Cov ntaub ntawv sib xws yog tsawg hauv cov ntaub ntawv tswj hwm. |
| Kev Sib Koom Cov Ntaub Ntawv | |
| Sib faib cov ntaub ntawv yooj yim dua hauv DBMS. | Sib faib cov ntaub ntawv nyuaj dua hauv kev tswj cov ntaub ntawv. |

| Data integrity yog siab hauv DBMS. | Hauv kev tswj cov ntaub ntawv, cov ntaub ntawv kev ncaj ncees yog qis. |
| Hloov kho, tshawb nrhiav, khaws cov ntaub ntawv yooj yim dua hauv DBMS vim yog cov lus nug. | Hloov kho, tshawb nrhiav, khaws cov ntaub ntawv nyuaj dua hauv kev tswj cov ntaub ntawv. |
| Kev Ruaj Ntseg | |
| Hauv DBMS, cov ntaub ntawv muaj kev nyab xeeb dua. | Cov ntaub ntawv tsis ruaj ntseg hauv cov ntaub ntawv tswj hwm. |
| txheej txheem thaub qab thiab rov qab | |
| Cov txheej txheem thaub qab thiab rov qab yog qhov nyuaj hauv DBMS. | txheej txheem thaub qab thiab rov qab yog yooj yim hauv cov ntaub ntawv kaw lus. |
| Tus naj npawb ntawm cov neeg siv | |
| DBMS yog tsim rau cov koom haum loj los txhawb ntau tus neeg siv. | Kev tswj cov ntaub ntawv tsim nyog rau cov koom haum me lossis ib tus neeg siv. |
Summary – DBMS vs File Management System
Qhov txawv ntawm DBMS thiab Cov Ntaub Ntawv Tswj Xyuas Cov Ntaub Ntawv yog tias DBMS khaws cov ntaub ntawv rau lub hard disk raws li tus qauv thaum lub kaw lus tswj cov ntaub ntawv khaws cov ntaub ntawv rau lub hard disk yam tsis siv cov qauv. DBMS muab cov ntaub ntawv sib qhia, thiab nws hloov tau yooj yim dua li kev tswj cov ntaub ntawv.
