Rhuav Nqa Qhov Sib Txawv Ntawm Ib Spreadsheet thiab Database
Ib qho ntawm cov tuam txhab ua lag luam tsis kam siv Microsoft Access yog qhov tsis muaj kev to taub ntawm qhov txawv ntawm ib qho kev tshaj tawm thiab cov ntaub ntawv database. Qhov no ua rau ntau tus neeg ntseeg tias kev nrhiav cov neeg siv cov ntaub ntawv, kev yuav khoom, thiab cov txheej txheem hauv cov ntaub ntawv khom nqi yog tsim nyog rau lawv cov kev xav tau. Qhov kawg tshwm sim yog tias nws tsis yooj yim los tswj cov tswj kev tswj hwm, cov ntaub ntawv tau ploj mus rau kev noj nyiaj txiag, thiab cov neeg ua hauj lwm yuam kev sau cov ntsiab lus tseem ceeb. Nrog me ntsis kev paub txog lub hwj chim thiab kev siv ntau lub database, nws yog qhov yooj yim rau cov lag luam me me kom pom thaum ib daim ntawv khom nqi tau txaus rau ib txoj hauj lwm thiab thaum lub database yuav tsum tsim kom muaj.
Nws yog ib qho tseem ceeb kom muaj kev nkag siab yooj yim txog ntawm cov ntaub ntawv database . Cov neeg feem coob tau nkag mus rau hauv cov ntaub ntawv ua ntej, zoo li cov nyob hauv cov tsev qiv ntawv pej xeem, tab sis tsuas yog siv lawv tsis ua kom tseeb tias cov ntawv khom nqi thiab cov kab ntawv sib txawv. Siv ob peb feeb kawm txog databases yuav pab ua qhov kev sib piv clearer.
Cov Koom Haum Ua Ntaub Ntawv
Tej zaum qhov feem ntau pom tseeb ntawm ib qho ntaub ntawv khom nqi thiab ib tug database yog txoj kev cov ntaub ntawv raug txhim kho. Yog hais tias cov ntaub ntawv tseem tiaj tus, ces ib daim ntawv khom nqi zoo tag nrho. Txoj kev txiav txim siab yog tias lub rooj sib hais plaub zoo tshaj plaws, nug seb puas los yog tsis tau tag nrho cov ntsiab lus ntawm cov ntaub ntawv tau yooj yim npaj rau daim duab lossis rooj? Piv txwv, yog tias ib lub tuam txhab xav txheeb xyuas cov nyiaj khwv tau txhua lub sij hawm hauv ib xyoo, ib daim ntawv tshaj tawm yog zoo tag nrho. Spreadsheets yog meant lis ntau ntawm tib hom ntaub ntawv, daim kuas qhov kev kawm ntawm ob peb lub ntsiab lus tseem ceeb.
Nyob rau hauv kev sib piv, databases muaj cov qauv ntaub ntawv sib paub. Yog tias tus neeg siv yuav tsum rub cov ntaub ntawv yuav muaj ntau yam ntxiv los xav txog. Piv txwv, yog tias ib lub tuam txhab xav taug qab nws cov nyiaj khwv tau txhua lub hlis thiab muab piv rau cov neeg sib tw hauv tsib xyoos dhau los, muaj kev sib raug zoo ntawm cov ntsiab lus ntawm cov ntaub ntawv no, tab sis tsis yog ib qho tseem ceeb. Ua ib zaug xwb cov lus qhia txog cov ntsiab lus yuav nyuaj, yog tias tsis ua. Databases yog tsim los ua kom yooj yim rau cov neeg siv los tsim cov ntawv qhia thiab khiav lus nug.
Complexity ntawm cov ntaub ntawv
Qhov yooj yim tshaj los sib piv seb cov ntaub ntawv yuav tsum tau ceev cia nyob rau hauv ib qho kev tshaj tawm los yog ib qho chaw khaws ntaub ntawv yog los saib cov txheej xwm li cas. Qhov no yuav pab kom nkag siab tias cov ntaub ntawv yuav tsum tau muab cov ntaub ntawv yog tias tus neeg siv tseem tsis meej.
Spreadsheet cov ntaub ntawv yeej yooj yim. Nws tuaj yeem yooj yim ntxiv rau ib qho los yog ib daim duab thiab ntxiv rau ib qho kev nthuav qhia yam tsis muaj cov lus qhia tawm. Nws yog ib qho yooj yim los tswj raws li nws ua raws li ob peb yam tseem ceeb ntawm tus lej numeric. Yog tias tsuas yog ob peb kab thiab txhua kab uas xav tau, cov ntaub ntawv zoo tshaj plaws muab khaws cia rau hauv ib qho kev tshaj tawm.
Databases tsev ntau hom ntau cov ntaub ntawv uas txhua tus muaj qee cov kev sib raug zoo rau lwm cov ntaub ntawv nyob rau hauv database. Piv txwv, cov tuam txhab khaws cov ntaub ntawv tseem ceeb ntawm lawv cov neeg tau txais kev pab, los ntawm cov npe thiab chaw nyob rau kev txiav txim thiab kev muag khoom. Yog hais tias ib tug neeg siv kev txeem txhiab txhiab tus kab rau hauv ib qho kev tshaj tawm, qhov muaj tseeb nws yuav tsum tau tsiv mus rau hauv ib lub database.
Repetition ntawm cov ntaub ntawv
Vim tias cov ntaub ntawv yuav tsum tau hloov tshiab tsis txhais hais tias yuav tsum muaj cov ntaub ntawv database. Puas yuav muaj tib cov ntaub ntawv tas li rov qab? Thiab yog lub lag luam uas xav tau tom qab cov txheej xwm lossis cov kev ua haujlwm?
Yog tias cov ntaub ntawv hloov pauv, tiam sis cov hom ntaub ntawv yog tib yam thiab cov kev sib tw nkaus xwb, cov lus qhia ntawd yog zaum hauv tsev. Ib qho piv txwv yog qhov nyiaj muag ntawm ib xyoo. Lub sij hawm yuav hloov thiab cov lej yuav hloov zuj zus, thiab yuav tsis muaj cov ntaub ntawv ntxiv.
Yog tias qee qhov chaw ntawm cov ntaub ntawv yuav zoo li qub, xws li cov ntaub ntawv qhia txog tus neeg, thaum lwm tus neeg hloov, xws li cov xaj thiab cov nqi ntawm cov nyiaj them poob haujlwm, qhov kev txiav txim yog qhov ua tiav. Qhov no yog thaum lub database yuav tsum raug siv. Kev ua muaj ntau yam sib txawv rau lawv, thiab sim mus saib lawv tag nrho yuav tsum tau muaj ib qho chaw database.
Cov ntaub ntawv lub hom phiaj tseem ceeb
Spreadsheets yog ib qho tseem ceeb rau cov sijhawm ua ntej uas tsis tas nrhiav kev sib txawv ntawm ntau qhov sib txawv. Rau cov haujlwm uas xav tau ib los yog ob daim phiaj los yog cov rooj rau kev nthuav qhia ua ntej yuav muab khaws cia, ib qho kev tshaj tawm yog qhov zoo tshaj los mus. Yog hais tias pawg neeg los yog lub tuam txhab xav tau xam cov txiaj ntsim tau thiab txiav txim siab feem pua, qhov twg yog qhov twg spreadsheets yog qhov tseem ceeb tshaj plaws.
Databases yog rau cov dej num ntev dua uas cov ntaub ntawv yuav raug siv rov ua dua. Yog tias sau ntawv thiab lus xav tau, cov ntaub ntawv yuav tsum muab xa mus rau hauv ib lub database. Spreadsheets tsis tsim los txhawm rau taug qab cov ntsiab lus, tsuas yog cov ntsiab lus tseem ceeb ntawm ob sab xwb.
Cov Pej Xeem Siv
Tus naj npawb ntawm cov neeg siv yuav xaus tau qhov kev txiav txim siab ntawm seb puas yuav siv ib qho kev tshaj tawm los yog hauv database. Yog tias ib qhov dej num xav kom ntau tus neeg siv tau hloov cov ntaub ntawv thiab hloov, qhov no yuav tsum tsis txhob ua nyob rau hauv daim ntawv khom nqi. Nws yog qhov yooj yim dua los tswj kom muaj kev tswj kom zoo nrog ib daim ntawv khom nqi. Yog tias muaj qee cov neeg siv los kho cov ntaub ntawv, feem ntau ntawm peb thiab rau, ib daim ntawv tshaj tawm yuav tsum txaus (tab sis nco ntsoov tsim cov cai ua ntej npaj siab nrog nws).
Yog hais tias tag nrho cov neeg koom rau hauv ib qhov project los yog tag nrho cov tuam tsev yuav tsum hloov, lub database yog qhov kev xaiv zoo. Txawm hais tias ib lub tuam txhab me me thiab tsuas muaj ib los yog ob tug neeg hauv fab tub ceev xwm tam sim no, xav txog tias pes tsawg leej neeg tuaj yeem mus xaus rau hauv chav haujlwm hauv tsib xyoos thiab nug seb lawv puas yuav xav hloov. Cov neeg siv ntau dua uas xav tau kev pab, qhov feem ntau cov ntaub ntawv yog qhov kev xaiv zoo.
Koj yuav tsum khaws cov ntaub ntawv ruaj ntseg rau hauv koj tus account. Yog hais tias muaj ntau cov ntaub ntawv rhiab heev uas xav tau kev ruaj ntseg, databases muab kev ruaj ntseg zoo dua. Ua ntej ua qhov khiav tawm, nco ntsoov nyeem txog cov teeb meem kev ruaj ntseg uas yuav tsum tau xav txog ua ntej tsim ib lub database.
Yog tias koj npaj txhij ua lub plhaub, nyeem peb qhov Tshaj Tawm Hloov Ntaub Ntawv rau Databases kom pib rau koj cov lus.
