Nov yog 5 cov txiaj ntsig ntawm sib cais ib daim ntawv thov ua tiers : Nws muab rau koj tus muaj peev xwm hloov kho tus technology pawg ntawm ib qib , tsis cuam tshuam lwm thaj chaw ntawm tus daim ntawv thov. Nws tso cai rau pab pawg txhim kho sib txawv rau txhua txoj haujlwm lawv tus kheej thaj chaw ntawm kev txawj ntse.
Ib yam li ib tug yuav nug, dab tsi yog 3 tier architecture?
A 3 - qib architecture yog hom software architecture uas yog tsim ntawm peb “ qib ”los yog “txheej txheem” ntawm kev xam pom. 3 - tier architectures muab ntau yam txiaj ntsig rau kev tsim khoom thiab kev loj hlob ib puag ncig los ntawm kev hloov pauv tus neeg siv interface, kev lag luam logic, thiab cov ntaub ntawv khaws cia cov khaubncaws sab nraud povtseg.
Tsis tas li ntawd, 2 tier thiab 3 tier architecture yog dab tsi? Yeej ntawm theem siab peb tuaj yeem hais qhov ntawd 2 - qib architecture yog Client server daim ntawv thov thiab 3 - qib architecture yog Web-based application. Cov ob - qib architecture yog zoo li tus neeg siv khoom server thov. Kev sib txuas lus ncaj qha yuav siv qhov chaw ntawm tus neeg siv khoom thiab server. Tsis muaj qhov nruab nrab ntawm cov neeg siv khoom thiab cov server.
Ib yam li ntawd, daim ntawv thov 3 qib yog dab tsi?
A 3 - daim ntawv thov qib architecture yog ib qho modular client-server architecture uas muaj kev nthuav qhia qib , ib daim ntawv thov qib thiab ib cov ntaub ntawv qib . Kev nthuav qhia qib sib txuas lus nrog lwm tus qib dhau daim ntawv thov program interface (API) hu.
Dab tsi yog peb theem neeg siv khoom / server architecture?
A peb - tier neeg / server yog ib hom multi- qib suav architecture nyob rau hauv uas tag nrho daim ntawv thov raug faib thoob plaws peb txawv xam txheej los yog qib . Nws faib cov kev nthuav qhia, daim ntawv thov logic thiab cov txheej txheem ua cov ntaub ntawv thoob plaws tus neeg siv khoom thiab server khoom siv.
