Lub npe hu ua 'software development life cycle', 6 cov kauj ruam no suav nrog kev npaj, tsom xam, tsim, kev tsim kho & kev siv, kev sim & kev xa tawm thiab kho.
Tsis tas li ntawd, dab tsi yog cov haujlwm tseem ceeb hauv kev txhim kho cov txheej txheem?
Cov cov haujlwm tseem ceeb hauv kev txhim kho systems yog tshuab tsom xam, tshuab tsim, programming, kuaj, hloov dua siab tshiab, ntau lawm, thiab tu.
Tsis tas li ntawd, cov theem ntawm kev txhim kho qhov system yog dab tsi? Feem ntau muaj rau theem nyob rau hauv lub voj voog no: xav tau kev txheeb xyuas, tsim, kev loj hlob thiab kev sim, kev siv, cov ntaub ntawv, thiab kev ntsuam xyuas.
System lifecycle
- Xav tau kev qhia.
- Kev tsom xam Feasibility.
- Kev txheeb xyuas qhov xav tau ntawm qhov system.
- System specification.
- Conceptual design review.
Tom qab ntawd, dab tsi yog 5 theem ntawm SDLC?
Ib qho kev sib cais ntawm cov theem muaj xws li 5: Kev Npaj, Kev Ntsuam Xyuas, Tsim, Kev nqis tes ua , thiab Maintenance. Lwm qhov kev sib cais tseem muaj 5 theem: Cov Kev Xav Tau, Tsim, Kev nqis tes ua , Test, Kho.
Dab tsi yog cov txheej txheem siv hauv kev txhim kho software?
Niaj hnub nimno kev loj hlob cov txheej txheem tuaj yeem piav qhia tsis meej raws li agile. Lwm yam txheej txheem suav nrog dej tsaws tsag, prototyping, iterative thiab incremental kev loj hlob , kauv kev loj hlob , ceev kev txhim kho daim ntawv thov , thiab programming heev.

Cov txheej txheem kev txhim kho tshuab yog dab tsi?
Ib txoj hauv kev txhim kho kab ke hais txog cov kauj ruam uas siv los tsim, npaj, thiab tswj cov txheej txheem ntawm kev tsim cov ntaub ntawv vim nws tsis yooj yim sua kom tsav mus rau qhov project mus rau computerize txoj kev yam tsis muaj kev ua haujlwm ua ntej
Dab tsi yog evolutionary software txhim kho txheej txheem?
Evolutionary qauv yog kev sib xyaw ua ke ntawm Iterative thiab Incremental qauv ntawm software txhim kho lub neej voj voog. Xa koj lub kaw lus nyob rau hauv qhov kev tso tawm loj, xa nws hauv cov txheej txheem nce ntxiv rau lub sijhawm yog qhov ua tiav hauv cov qauv no. Yog li ntawd, cov khoom siv software hloov kho nrog lub sijhawm
Dab tsi yog ob qho software tseem ceeb rau kev txhim kho Android?
Cov Kev Xav Tau rau Android Kev Txhim Kho? Windows/Linux/Mac powered PC. Lub operating system yog tus ntsuj plig ntawm lub PC. Pom zoo processor. Ntau tshaj i3, i5 lossis i7 cov neeg tsim khoom yuav tsum txhawj xeeb txog qhov ceev ntawm cov processor thiab cov lej ntawm cov tub ntxhais kawm. IDE (Eclipse lossis Android Studio) Android SDK. Java. Xaus
Vim li cas kev sim tsav kev txhim kho ua rau kev txhim kho sai dua?
TDD pab tsim kom zoo dua modularized, extensible thiab saj zawg zog code. Test Driven Development mus kom ze tsav cov pab pawg Agile los npaj, tsim thiab sim cov chav me me kom sib koom ua ke ntawm theem siab. Raws li txoj hauv kev no, cov tswv cuab cuam tshuam xa thiab ua tau zoo dua vim tias tau tsom mus rau lub tsev me me
Dab tsi yog qhov haujlwm ntawm OSI txheej txheej txheej txheej txheej txheem router ua haujlwm li cas?
Hauv Cov Qauv Qhib Kev Sib Txuas Sib Txuas (OSI) kev sib txuas lus, txheej txheej txheej txheem nyob ntawm Txheej 5 thiab tswj kev teeb tsa thiab rhuav tshem ntawm kev sib txuas ntawm ob qhov kev sib txuas lus kawg. Kev sib txuas lus ntawm ob qhov kawg yog hu ua kev sib txuas
