Cov tsis yog - kev xav tau (NFRs) txhais cov yam ntxwv xws li muaj, kev tswj xyuas, kev ua tau zoo, kev ntseeg tau, kev ua kom muaj zog, kev ruaj ntseg, thiab kev siv tau.
Ntawm no, cov piv txwv ntawm cov kev cai tsis ua haujlwm yog dab tsi?
Qee qhov kev xav tau uas tsis ua haujlwm yog:
- Kev ua tau zoo - piv txwv li Lub Sijhawm Teb, Kev Tshaj Tawm, Kev Siv, Static Volumetric.
- Scalability.
- Muaj peev xwm.
- Muaj.
- Kev ntseeg tau.
- Rov qab tau.
- Kev ruaj ntseg.
- Kev pabcuam.
Ib yam li ntawd, dab tsi yog usability nyob rau hauv cov kev cai uas tsis haumxeeb? Cov kev xav tau tsis ua haujlwm (NFRs) txhais cov txheej txheem xws li kev ruaj ntseg, kev cia siab, kev ua tau zoo, kev tswj xyuas, kev ua kom muaj peev xwm, thiab kev siv tau . Lawv ua hauj lwm asconstraints los yog txwv nyob rau hauv lub tsim ntawm lub system nyob rau hauv lub sib txawv backlogs. Lawv xyuas cov kev siv tau andeffectiveness ntawm tag nrho cov system.
Ntxiv rau qhov no, dab tsi yog cov kev cai uas tsis ua haujlwm?
Hauv systems engineering thiab kev xav tau engineering, ib tsis yog - kev xav tau kev ua haujlwm (NFR) yog a kev xav tau uas qhia meej txog cov txheej txheem uas tuaj yeem siv los txiav txim rau kev ua haujlwm ntawm ib qho system, es tsis yog tus cwj pwm tshwj xeeb. Lawv tau sib piv nrog kev xav tau uas txhais cov cwj pwm tshwj xeeb lossis kev ua haujlwm.
Leej twg txhais cov kev cai tsis ua haujlwm?
Cov kev xav tau tsis ua haujlwm . NonfunctionalRequirements (NFRs) txhais system attributes xws li kev ruaj ntseg, kev cia siab, kev ua tau zoo, kev ruaj ntseg, scalability, thiab usability. Lawv ua haujlwm raws li kev txwv lossis kev txwv ntawm kev tsim qauv ntawm lub kaw lus hla ntawm qhov sib txawv backlogs.

Vim li cas koj yuav tsum tshuaj xyuas cov cav tsis tu ncua thiab koj yuav tsum tswj txoj haujlwm no li cas?
Los ntawm kev saib xyuas kev ruaj ntseg, lub hom phiaj ntawm lub cav yog ua raws li tus chij liab thaum muaj ib yam dab tsi phem tshwm sim. Kev tshuaj xyuas cov cav tsis tu ncua tuaj yeem pab txheeb xyuas qhov kev tawm tsam tsis zoo ntawm koj lub cev. Muab qhov loj ntawm cov ntaub ntawv cav tsim los ntawm cov tshuab, nws yog qhov ua tsis tau zoo los tshuaj xyuas tag nrho cov cav no manually txhua hnub
Dab tsi yog qhov kev teeb tsa tseem ceeb uas cov neeg siv yuav tsum tau qhia kom khiav MapReduce txoj haujlwm?
Lub ntsiab configuration tsis uas cov neeg siv yuav tsum tau qhia nyob rau hauv "MapReduce" lub moj khaum yog: Txoj hauj lwm input qhov chaw nyob rau hauv cov ntaub ntawv faib. Txoj hauj lwm tso zis qhov chaw nyob rau hauv lub faib ntaub ntawv system. Input hom ntaub ntawv. Tso zis hom ntaub ntawv. Chav kawm uas muaj daim ntawv qhia ua haujlwm. Chav kawm uas muaj qhov txo qis ua haujlwm
Dab tsi VM Series koj yuav tsum xav txog yog tias koj xav tau cov ntawv thov host uas xav tau kev ua haujlwm siab IO rau cov ntaub ntawv tsis tu ncua?
Teb: VM series uas koj yuav tsum yog xav txog yog tias koj xav tau txais cov ntawv thov uas xav tau kev ua haujlwm siab rau cov ntaub ntawv tsis tu ncua yog VMware workstation, Oracle VM virtual box lossis Microsoft Azure suav. Cov khoom siv no muaj qhov yooj yim tshaj plaws ntawm kev ua haujlwm hosting
Dab tsi yog qhov yuav tsum tau rau kev khiav hauj lwm qhov system?
Qhov System Requirements Operating System. Tsawg kawg CPU lossis processor ceev. Tsawg kawg GPU lossis video nco. Yam tsawg kawg nkaus lub cim xeeb (RAM) Qhov tsawg kawg nkaus pub dawb. Audio hardware (suab card, hais lus, thiab lwm yam)
Dab tsi yog qhov yuav tsum tau ua rau kev ntsuas kev ua haujlwm?
Lub hauv paus yuav tsum tau ua ua ntej rau kev ntsuas kev ua tau zoo suav nrog kev nkag siab txog daim ntawv thov nyob rau hauv kev sim, txheeb xyuas cov kev xav tau ntawm kev ua haujlwm xws li lub sijhawm teb, qhov qub thiab qhov siab tshaj plaws, cov qauv tsheb sib tw, thiab xav tau lossis xav tau sijhawm
