Qhov Tseem Ceeb Qhov txawv - SDLC vs Agile Methodology
Qhov sib txawv tseem ceeb ntawm SDLC thiab Agile Methodology yog SDLC yog cov txheej txheem ntawm kev faib cov software tsim ua haujlwm rau hauv cov theem sib txawv los tsim thiab tsim cov software zoo thaum Agile Methodology yog SDLC qauv. Agile Methodology yog ib qho kev sib xyaw ua ke ntawm cov txheej txheem rov ua dua thiab cov txheej txheem ntxiv uas tsom rau cov txheej txheem hloov kho thiab cov neeg siv khoom txaus siab los ntawm kev xa khoom sai ntawm cov khoom lag luam software.
SDLC yog dab tsi?
SDLC sawv cev rau Software Development Life Cycle. Thaum tsim software, muaj qee theem uas yuav tsum tau ua raws. Txhua lub koom haum txhim kho software ua raws SDLC rau qhov project software. Muaj ntau theem hauv SDLC. Ib qho kev nkag siab yooj yim ntawm qhov teeb meem raug txheeb xyuas hauv theem kev npaj. Tshawb nrhiav cov kev pheej hmoo cuam tshuam nrog qhov project, kev nyuaj siab, cov peev txheej, kev tsim kho kev siv zog kuj raug txheeb xyuas nyob rau theem no.
Nyob rau theem yuav tsum tau ua, thawj qhov haujlwm yog los sau thiab tshuaj xyuas cov cai. Tau txais cov neeg siv khoom nkag, ntsib cov thawj coj loj thiab tau txais cov ntsiab lus ntawm kev muag khoom, thiab kev lag luam tshwm sim hauv kev xav tau sib sau ua ke. Cov kev xav tau sib sau ua ke yuav tsum tau sau tseg kom raug. Cov ntaub ntawv no yog hu ua Software Requirement Specification (SRS). Nws muaj cov khoom yuav tsum tau tsim thiab tsim thaum lub sij hawm lub neej voj voog.
Tus tsim software yog muab los ntawm SRS. Ntau tshaj ib txoj hauv kev tsim qauv rau cov khoom lag luam yog npaj thiab sau tseg hauv Daim Ntawv Qhia Txog Kev Tsim Qauv (DDS). Nyob rau hauv theem no, tag nrho cov architectural modules, cov ntaub ntawv txaus sawv cev nrog rau sab nraud modules thiab lwm yam yog tsim.
Nyob rau hauv qhov kev siv, qhov project yog siv los tsim cov lus programming. Ntau yam programming cuab yeej xws li compilers, txhais lus, code editors, IDEs, thiab debuggers yuav siv tau los sau thiab sim cov kev pab cuam. Cov lus programming tuaj yeem xaiv raws li daim ntawv thov. Chav ntsuas rau cov qauv tsim tau ua tiav nyob rau theem no.
Kev xeem yog cov txheej txheem ntawm kev txheeb xyuas thiab lees paub tias qhov kev pabcuam software ua haujlwm raws li qhov xav tau. Nws yog siv los xyuas seb qhov project kawg tau los rau qhov xav tau. Kev ntsuam xyuas muaj xws li kev sib koom ua ke, kev sim ntsuas thiab lwm yam. Kev sib xyaw ua ke yog ua kev sim ntawm ob lub modules. Qhov kev sim ntsuas yog qhov kev sim ua tiav.
Daim duab 01: SDLC
Thaum kawg, cov khoom raug tso tawm rau lub khw. Raws li cov neeg siv khoom tawm tswv yim, cov yam ntxwv tshiab tuaj yeem ntxiv rau cov khoom. Kev saib xyuas thiab kev pabcuam yuav tsum tau muab rau cov neeg siv khoom uas twb muaj lawm. Cov no yog cov theem tseem ceeb ntawm SDLC.
Dab tsi yog Agile Methodology?
Thaum lub sijhawm txhim kho software, yuav tsum ua raws li software txhim kho lub neej voj voog qauv. Cov qauv no hu ua Software Development Process Model. Txhua tus txheej txheem ua raws qee cov kauj ruam tshwj xeeb rau nws hom kom ua tiav qhov project software. Qee qhov piv txwv ntawm SDLC qauv yog cov qauv dej tsaws tsag, cov qauv rov ua dua, cov qauv kauv, v qauv, qauv qauv, Kev Tsim Kho Kev Siv nrawm, thiab lwm yam.
Agile methodology kuj yog tus qauv SDLC. Nws yog kev sib xyaw ua ke ntawm iteration thiab incremental txheej txheem qauv. Cov qauv no yuav pab kom yoog raws cov kev hloov pauv hauv cov kev xav tau. Nyob rau hauv cov qauv no, qhov project yog tawg mus rau hauv ob peb modules. Xav tias qhov project tau tawg ua peb lub modules xws li A, B, thiab C. Thawj module A mus txog kev npaj, kev sib sau ua ke thiab kev tsom xam, tsim, siv thiab sim. Thaum nws ua tiav, B module pib. Nws kuj mus dhau theem ib yam li lub module A. Thaum B tiav lawm, module C pib. Thaum kawg ntawm qhov rov ua dua, ib qho kev ua haujlwm tuaj yeem muab rau tus neeg siv khoom.
Muaj ntau qhov zoo ntawm Agile. Nyob rau hauv cov qauv dej tsaws tsag ib txwm muaj, ib zaug cov kev cai tau teev tseg, lawv tsis tuaj yeem hloov pauv. Tab sis hauv Agile, cov kev xav tau tuaj yeem hloov pauv. Kuj tseem muaj kev sib koom tes ntau dua ntawm tus tsim tawm thiab cov neeg siv khoom. Nws txhim kho kev ua haujlwm pab pawg thiab ua rau qhov project yooj yim los tswj. Zuag qhia tag nrho, Agile yog tus qauv SDLC nrov vim nws yooj yim thiab yoog raws. Tej zaum nws yuav tsis haum rau ib qhov project complex. Lwm qhov tsis zoo yog tias tus neeg siv khoom tuaj yeem hloov pauv cov kev xav tau ib txwm muaj thiab nws yog qhov tsim nyog kom muaj tus thawj coj nrawm los coj txoj haujlwm.

Summary – SDLC vs Agile Methodology
Kab lus no tau tham txog qhov sib txawv ntawm SDLC thiab Agile. Qhov txawv ntawm SDLC thiab Agile Methodology yog SDLC yog cov txheej txheem ntawm kev faib cov software tsim ua haujlwm rau hauv cov theem sib txawv los tsim thiab tsim cov software zoo thaum Agile Methodology yog SDLC qauv.
