DBMS vs File System
DBMS (Database Management System) thiab Cov Ntaub Ntawv Txheej Txheem yog ob txoj hauv kev uas tuaj yeem siv los tswj, khaws, khaws thiab tswj cov ntaub ntawv. Cov Ntaub Ntawv Cov Ntaub Ntawv yog ib qho ntawm cov ntaub ntawv raw cov ntaub ntawv khaws cia hauv lub hard drive whereas DBMS yog ib pob ntawm cov ntawv thov uas tau mob siab rau kev tswj cov ntaub ntawv khaws cia hauv databases. Nws yog kev sib koom ua ke siv los tswj cov ntaub ntawv digital, uas tso cai rau kev khaws cov ntsiab lus database, tsim / tu cov ntaub ntawv, tshawb nrhiav thiab lwm yam haujlwm. Ob lub tshuab siv tau los tso cai rau tus neeg siv ua haujlwm nrog cov ntaub ntawv zoo ib yam. Cov Ntaub Ntawv System yog ib txoj hauv kev ntxov tshaj plaws ntawm kev tswj cov ntaub ntawv. Tab sis vim qhov tsis txaus nyob rau hauv kev siv File System los khaws cov ntaub ntawv hluav taws xob, Database Management Systems tuaj rau siv qee lub sijhawm tom qab, vim lawv muab cov txheej txheem los daws cov teeb meem ntawd. Tab sis nws yuav tsum tau muab sau tseg tias, txawm nyob rau hauv DBMS, cov ntaub ntawv yog thaum kawg (lub cev) khaws cia nyob rau hauv ib co hom ntawm cov ntaub ntawv.
File System
Raws li tau hais los saum no, hauv Cov Ntaub Ntawv Cov Ntaub Ntawv Hluav Taws Xob cov ntaub ntawv ncaj qha khaws cia rau hauv cov ntaub ntawv. Yog tias tsuas yog ib lub rooj khaws cia hauv cov ntaub ntawv, lawv raug hu ua cov ntaub ntawv tiaj tus. Lawv muaj qhov tseem ceeb ntawm txhua kab sib cais nrog tus lej tshwj xeeb xws li commas. Txhawm rau nug qee cov ntaub ntawv random, ua ntej nws yuav tsum tau txheeb xyuas txhua kab thiab thauj mus rau ib qho array ntawm lub sijhawm khiav. Tab sis rau cov ntaub ntawv no yuav tsum tau nyeem ua ntu zus (vim tias, tsis muaj kev tswj hwm hauv cov ntaub ntawv), yog li nws tsis muaj txiaj ntsig thiab siv sijhawm. Lub nra ntawm kev nrhiav cov ntaub ntawv tsim nyog, mus txog cov ntaub ntawv (kab los ntawm kab), tshawb xyuas qhov muaj nyob ntawm qee cov ntaub ntawv, nco ntsoov cov ntaub ntawv / cov ntaub ntawv hloov kho yog nyob ntawm tus neeg siv. Tus neeg siv yuav tsum ua txhua txoj haujlwm manually lossis yuav tsum tau sau ib tsab ntawv uas ua rau lawv tau txais kev pab los ntawm kev tswj cov ntaub ntawv muaj peev xwm ntawm lub operating system. Vim yog cov laj thawj no, Cov Ntaub Ntawv Cov Ntaub Ntawv tau yooj yim rau cov teeb meem loj xws li kev tsis sib xws, tsis muaj peev xwm ua tau zoo, kev cais cov ntaub ntawv, kev hem thawj ntawm kev ncaj ncees thiab tsis muaj kev ruaj ntseg.
DBMS
DBMS, qee zaum tsuas yog hu ua tus thawj tswj hwm database, yog ib qho kev sau ntawm cov khoos phis tawj uas tau mob siab rau kev tswj hwm (piv txwv li lub koom haum, khaws cia thiab rov qab) ntawm tag nrho cov databases uas tau teeb tsa hauv qhov system (piv txwv li hard drive lossis network). Muaj ntau hom Database Management Systems uas twb muaj lawm nyob rau hauv lub ntiaj teb no, thiab ib co ntawm lawv yog tsim los rau kev tswj kom zoo databases configured rau tej lub hom phiaj. Cov lag luam nrov tshaj plaws Database Management Systems yog Oracle, DB2 thiab Microsoft Access. Tag nrho cov khoom no muab kev faib tawm ntawm ntau theem ntawm cov cai rau cov neeg siv sib txawv, ua rau nws muaj peev xwm rau DBMS los tswj hwm hauv nruab nrab los ntawm ib tus thawj coj lossis muab faib rau ntau tus neeg sib txawv. Muaj plaub lub ntsiab lus tseem ceeb nyob rau hauv ib qho Database Management System. Lawv yog cov qauv lus, cov qauv ntaub ntawv, lus nug thiab cov txheej txheem rau kev lag luam. Cov qauv qauv txhais cov lus ntawm txhua qhov chaw khaws cia hauv DBMS. Tam sim no ntau txoj hauv kev nrov xws li hierarchal, network, kev sib raug zoo thiab cov khoom yog nyob rau hauv kev xyaum. Cov qauv ntaub ntawv pab npaj cov ntaub ntawv xws li cov ntaub ntawv tus kheej, cov ntaub ntawv, cov teb thiab lawv cov ntsiab lus thiab cov khoom xws li kev tshaj tawm pom. Cov lus nug cov ntaub ntawv tso cai rau kev tswj hwm thiab kev ruaj ntseg ntawm cov ntaub ntawv. Nws saib xyuas cov ntaub ntawv nkag mus, nkag mus rau cov cai rau cov neeg siv sib txawv, thiab cov txheej txheem ntxiv cov ntaub ntawv rau qhov system. SQL yog ib hom lus nug nrov uas yog siv hauv Relational Database Management Systems. Thaum kawg, cov txheej txheem uas tso cai rau kev lag luam pab sib koom ua ke thiab ntau yam. Cov txheej txheem ntawd yuav ua kom cov ntaub ntawv qub yuav tsis raug hloov kho los ntawm ntau tus neeg siv tib lub sijhawm, yog li khaws cov ntaub ntawv ncaj ncees hauv kev sib tw. Tsis tas li ntawd, DBMSs muab cov ntaub ntawv thaub qab thiab lwm yam khoom siv. Nrog rau tag nrho cov kev nce qib no nyob rau hauv qhov chaw, DBMS daws yuav luag txhua yam teeb meem ntawm File System, tau hais los saum toj no.
Qhov txawv ntawm DBMS thiab Cov Ntaub Ntawv System
Hauv Cov Ntaub Ntawv Cov Ntaub Ntawv, cov ntaub ntawv siv los khaws cov ntaub ntawv thaum, cov ntaub ntawv khaws cia yog siv los khaws cov ntaub ntawv hauv DBMS. Txawm hais tias File System thiab DBMS yog ob txoj hauv kev los tswj cov ntaub ntawv, DBMS kom meej meej muaj ntau yam zoo dua File Systems. Feem ntau thaum siv File System, feem ntau cov dej num xws li khaws cia, rov qab thiab tshawb nrhiav tau ua tiav manually thiab nws yog qhov nyuaj heev thaum DBMS yuav muab txoj hauv kev ua kom tiav cov haujlwm no. Vim li no, siv File System yuav ua rau muaj teeb meem xws li cov ntaub ntawv kev ncaj ncees, cov ntaub ntawv tsis sib xws thiab cov ntaub ntawv kev ruaj ntseg, tab sis cov teeb meem no tuaj yeem zam tau los ntawm kev siv DBMS. Tsis zoo li Cov Ntaub Ntawv Cov Ntaub Ntawv, DBMS yog qhov ua tau zoo vim tias kev nyeem kab los ntawm kab tsis tas yuav tsum tau thiab qee qhov kev tswj hwm hauv qhov chaw.
