Qhov Tseem Ceeb Qhov Sib Txawv - Qhov Kev Ua Haujlwm vs Qhov Kev Ntsuas Qhov Ntsuas
System mus kom ze thiab kev tsom xam yog ob lo lus nquag siv thaum tham txog kev txhim kho lub neej voj voog. Lub kaw lus yog ib lub koom haum ua haujlwm kom ua tiav qee yam haujlwm lossis cov haujlwm. Lub kaw lus muaj cov tswv yim, tso zis, ua, tawm tswv yim thiab tswj. Ib qho system tuaj yeem muaj ntau lub subsystems lossis cov khoom siv. Lub kaw lus muaj ntau yam khoom xws li kev sib txuas, kev sib koom tes, kev sib koom tes, kev tswj hwm thiab lwm yam. Yuav tsum muaj kev sib txuas ntawm subparts ntawm lub system. Yuav tsum muaj kev sib koom tes thiab kev sib koom tes ntawm cov subparts ntawm qhov system. Thaum tsim software, muaj qee yam txheej txheem ua raws li lub koom haum. Nws hu ua System Development Life Cycle (SDLC). Nws pab tsim, tsim thiab sim cov software zoo. Txoj hauv kev thiab kev txheeb xyuas qhov system yog ob nqe lus hais txog SDLC. Cov theem tseem ceeb ntawm SDLC yog qhov muaj peev xwm kawm, kev txheeb xyuas qhov system, kev tsim qauv, kev tsim kho, kev sim, kev saib xyuas. Yog li, kev txheeb xyuas qhov system yog theem ntawm SDLC. Nws qhia meej tias qhov system tuaj yeem ua li cas. System Approach yog ib txoj hauv kev los daws qhov teeb meem. Qhov sib txawv tseem ceeb ntawm System mus kom ze thiab kev tsom xam yog qhov System mus kom ze yog ib txoj hauv kev daws teeb meem uas tuaj yeem siv rau hauv System Development Life Cycle (SDLC) thaum kev txheeb xyuas qhov system yog ib theem ntawm System Development Life Cycle.
Txoj Kev Ua Haujlwm yog dab tsi?
Ib lub cev qhia txog ntau yam khoom thiab cov yam ntxwv. Txhua qhov system muaj qee lub hom phiaj kom ua tiav. Lub kaw lus muaj cov tswv yim, tso zis thiab ua cov khoom siv kom ua tiav ib qho haujlwm lossis cov haujlwm. Feem ntau, ib qho system tau tsim nrog qee cov kev cai thiab cov cai. Ua ntej, qhov teeb meem yog txhais siv qhov system orientation. Tom qab ntawd yuav tsum nrhiav kev daws teeb meem los daws qhov teeb meem. Ib qho system muaj ib thaj tsam tshwj xeeb. Ib tug yam ntxwv tseem ceeb ntawm ib tug system yog hais tias nws yuav muab faib ua subsystems.
Thaum siv txoj kev daws teeb meem tsim los daws qhov teeb meem, nws yog hu ua scientific method. Txoj kev no muaj ob peb kauj ruam. Ua ntej, nws yog ib qho tseem ceeb los txheeb xyuas qhov tshwm sim ntawm lub ntiaj teb tiag. Tom qab ntawd, yuav tsum tsim ib qho kev xav txog qhov ua rau thiab qhov tshwm sim ntawm qhov tshwm sim. Tom qab ntawd, yuav tsum sim qhov kev xav nrog kev sim. Tom qab ntsuas cov txiaj ntsig ntawm qhov kev sim, nws yog ib qho yooj yim los mus txiav txim siab txog qhov kev xav. Feem ntau, txoj hauv kev mus kom ze yog txheej txheem kev daws teeb meem.
Muaj ntau yam kev daws teeb meem thiab nrhiav kev daws teeb meem. Ua ntej, yuav tsum txheeb xyuas qhov teeb meem yog dab tsi, siv qhov system xav. Kev xav hauv kev xav yog nrhiav cov tshuab, subsystems thiab cov khoom ntawm cov tshuab hauv txhua qhov xwm txheej raws li kev xav. Tom qab ntawd, lwm txoj kev daws teeb meem tuaj yeem ntsuas thiab tsim kho. Tawm ntawm tag nrho, yuav tsum xaiv cov kev daws teeb meem zoo tshaj plaws los daws qhov teeb meem. Thaum kawg, cov kev xaiv xaiv yog tsim thiab siv. Txoj kev npaj ua kom tiav muaj cov peev txheej, cov haujlwm thiab lub sijhawm xav tau los ua kom tiav qhov kev ua tiav.
Dab tsi yog qhov Kev Ntsuam Xyuas?
Kev siv txoj hauv kev mus rau qhov kev qhia xov xwm hu ua System Development Lifecycle (SDLC). Cov kauj ruam tseem ceeb ntawm SDLC yog kev npaj, kev tshuaj xyuas, kev tsim qauv, kev tsim kho, kev sim thiab kev saib xyuas. Hauv kev npaj, qhov Scope ntawm qhov teeb meem raug txheeb xyuas. Cov peev txheej, nqi, sijhawm thiab lwm yam raug txiav txim siab nyob rau theem no.
Cov kauj ruam tom ntej yog kev txheeb xyuas qhov system. Nws yog ib qho kev kawm tob txog kev ua haujlwm uas tsim nyog rau cov neeg siv kawg. Kev txheeb xyuas qhov system yog los kawm txog qhov system thiab txheeb xyuas cov hom phiaj. Nws yog txheej txheem ntawm kev sau thiab txhais cov lus tseeb, txheeb xyuas qhov teeb meem thiab decomposition ntawm ib qho system rau hauv nws cov khoom. Kev txheeb xyuas qhov system pab kom ntseeg tau tias txhua qhov haujlwm ua haujlwm kom ua tiav txoj haujlwm. Cov txiaj ntsig ntawm kev txheeb xyuas qhov system yog cov tswv yim rau kev tsim qauv.
Nyob rau hauv kev tsim qauv, nws tsim ib qho kev qhia tshwj xeeb. Lub tswv yim rau qhov kev tsim qauv yog qhov kev xav tau ntawm kev tshawb xyuas qhov system. Cov qauv tsim muaj cov txheej txheem tsim, cov ntaub ntawv tsim thiab tus neeg siv interface tsim. Tus txheej txheem tsim yog tus txheej txheem tsim uas tsom rau kev tsim cov khoos phis tawj tsim nyog rau cov txheej txheem npaj. Cov ntaub ntawv tsim qauv koom nrog ua qauv ER daim duab ntawm lub system. Tus neeg siv interface tsim tsom rau kev sib cuam tshuam ntawm cov neeg siv kawg thiab qhov system. Nws muaj cov ntxaij vab tshaus tso saib kom ua haujlwm ntawm qhov system. Lub sijhawm xeem yog txhawm rau txheeb xyuas thiab txheeb xyuas seb cov txiaj ntsig ntawm qhov kev thov tau ua tau raws li cov hom phiaj xav tau. Nyob rau theem kev saib xyuas, cov yam ntxwv tshiab tuaj yeem ntxiv los txhim kho lub system.
Dab tsi yog qhov zoo sib xws ntawm Kev Ua Haujlwm thiab Kev Ntsuam Xyuas Qhov Txheej Txheem?
Ob Txoj Kev Ua Haujlwm thiab Kev Ntsuam Xyuas Txheej Txheem yog cuam tshuam nrog Kev Txhim Kho Lub Neej Cycle (SDLC)
Dab tsi yog qhov txawv ntawm Qhov Kev Ntsuas thiab Kev Ntsuas Qhov Ntsuas?
