Functional vs Non Functional Requirements
Qhov sib txawv tseem ceeb ntawm kev ua haujlwm thiab tsis ua haujlwm yog qhov yuav tsum tau ua haujlwm piav qhia seb lub kaw lus yuav tsum ua li cas thaum cov kev cai tsis ua haujlwm piav qhia txog kev ua haujlwm li cas.
Hauv Software Engineering, cov software yuav tsum tau tsom mus rau cov kev xav tau uas yuav tsum tau daws los ntawm software. Thaum tsim software, thawj kauj ruam yog los sau cov cai. Nws yog ib qho ntawm cov kauj ruam tseem ceeb tshaj plaws vim tias tag nrho cov khoom nyob ntawm qhov kev xav tau sib sau ua ke. Thaum cov kev xav tau sib sau ua ke, lawv tau txheeb xyuas thiab sau rau hauv Software Requirement Specification (SRS). Cov Kev Xav Tau Software tuaj yeem muab faib ua ob ntu raws li Kev Xav Tau thiab Tsis Ua Haujlwm.
Cov Kev Xav Tau Ua Haujlwm yog dab tsi?
Cov kev cai uas qhia meej txog kev ua haujlwm ntawm software yog lub npe hu ua cov kev cai ua haujlwm. Cov kev xav tau ua haujlwm hloov ntawm ib qhov project mus rau lwm qhov. Lawv txhais cov kev ua haujlwm tau muab los ntawm cov tshuab lossis cov khoom siv.
Daim duab 01: Kev Txhim Kho Software
Xaiv lub tsev kho mob tswj hwm. Nws tuaj yeem muaj ntau lub modules xws li tus ID nkag mus module, tus neeg mob module, tus kws kho mob module, teem caij module, qhia module thiab them nqi module. Tus ID nkag mus module yuav tsum ua tiav nkag mus rau hauv lub kaw lus thaum muab tus username thiab password kom raug. Tus neeg mob module yuav tsum txuag, kho thiab tshem tawm cov ntaub ntawv tus neeg mob. Tus kws kho mob module yuav tsum txuag, kho thiab tshem tawm cov ntaub ntawv kws kho mob. Lub sijhawm teem sijhawm yuav tsum teem sijhawm, rov teem sijhawm thiab tshem tawm cov sijhawm teem tseg. Daim ntawv qhia module yuav tsum tsim cov ntaub ntawv kho mob. Cov nqi them nqi yuav tsum tsim cov nqi them nqi. Cov no yog qee qhov yuav tsum ua haujlwm rau lub tsev kho mob tswj hwm.
Dab tsi yog Cov Kev Xav Tau Tsis Ua Haujlwm?
Cov kev cai uas tsis muaj feem cuam tshuam rau kev ua haujlwm ntawm software poob rau hauv pawg tsis ua haujlwm. Lawv txhais cov yam ntxwv xav tau ntawm software. Cov neeg siv tuaj yeem ua qhov kev xav txog lawv. Ntau tus neeg siv tau txhawj xeeb txog kev tau txais cov kev cai tsis ua haujlwm tshwj xeeb rau cov tshuab loj.
Ib lub tsev kho mob tswj hwm yuav tsum muaj cov cai hauv qab no tsis ua haujlwm. Kev nrawm yog qhov xav tau ntau heev. Lub kaw lus yuav tsum ua cov ntaub ntawv hauv lub sijhawm teb tsawg kawg nkaus. Lub kaw lus yuav tsum muaj kev ruaj ntseg. Cov ntaub ntawv yuav tsum nkag tau tsuas yog los ntawm cov neeg siv tau tso cai. Nws yuav tsum yooj yim khaws cia. Cov software yuav tsum yog cov khoom ua haujlwm thiab siv tau. Cov ntaub ntawv yuav tsum txhim khu kev qha thiab muaj thaum tsim nyog. Yog li ntawd, kev tswj xyuas hauv tsev kho mob yuav tsum tsis muaj qhov yuav tsum tau ua xws li kev ua haujlwm, kev ruaj ntseg, kev tswj xyuas, kev siv tau, kev ntseeg tau thiab muaj.
Qhov txawv ntawm Kev Ua Haujlwm thiab Tsis Ua Haujlwm yog dab tsi?
Functional vs Non Functional Requirements |
|
| Cov Kev Xav Tau Ua Haujlwm yog qhov yuav tsum tau txhais cov haujlwm ntawm lub kaw lus lossis nws cov kab ke. | Cov Kev Xav Tau Tsis Ua Haujlwm yog qhov yuav tsum tau hais qhia cov txheej txheem uas tuaj yeem siv los txiav txim rau kev ua haujlwm ntawm qhov system. |
| Cov kev xav tau ua haujlwm yog siv los piav txog kev ua haujlwm ntawm lub system. | Cov kev cai tsis ua haujlwm piav qhia txog cov yam ntxwv zoo lossis cov yam ntxwv zoo. |
Summary – Functional vs Non Functional Requirements
Kab lus no tau tham txog qhov sib txawv ntawm ob pawg ntawm software yuav tsum tau ua. Qhov txawv ntawm kev ua haujlwm thiab tsis ua haujlwm yog qhov yuav tsum tau ua haujlwm piav qhia txog qhov system yuav tsum ua li cas thaum cov kev cai tsis ua haujlwm piav qhia txog qhov system ua haujlwm li cas.
