Systems tsim engineering yog tus cwj pwm los ntawm nws txoj kev xav, txoj hauv kev, thiab txoj hauv kev los daws cov teeb meem uas muaj ntau qhov kev qhuab qhia. Los ntawm kev xav txog lub hom phiaj thiab cov kev xav tau kev ua tau zoo a tsim kev daws teeb meem yog tsim uas ua tau raws li cov kev xav tau ntawm cov neeg siv khoom, cov neeg siv khoom thiab lub koom haum.
Cov lus nug tseem yog, dab tsi yog qhov system engineering mus kom ze?
Systems engineering yog methodical, qhuab ntuas mus kom ze rau kev tsim, kev ua tiav, kev tswj xyuas, kev ua haujlwm, thiab kev so haujlwm ntawm a qhov system . A“ qhov system ” yog ib qho kev tsim lossis sau cov ntsiab lus sib txawv uas ua ke tsim cov txiaj ntsig tsis tau los ntawm cov ntsiab lus ib leeg.
Kuj Paub, qhov txheej txheem tsim qauv yog dab tsi? Kev tsim qauv yog cov txheej txheem ntawm tsim cov ntsiab lus ntawm a qhov system xws li thearchitecture, modules thiab Cheebtsam, qhov sib txawv interfaces ntawm cov Cheebtsam thiab cov ntaub ntawv mus txog qhov ntawd qhov system.
Hauv qhov no, qhov system tsim thiab nws hom yog dab tsi?
Kev tsim qauv muab faib ua ob hom :Logical Tsim Tus logical tsim ntawm a qhov system muaj feem xyuam rau ib tug abstract sawv cev ntawm tus cov ntaub ntawv ntws, inputs thiab outputs ntawm qhov system . Qhov no feem ntau yog ua los ntawm kev ua qauv, uas suav nrog kev simplistic (thiab qee zaum graphical) sawv cev ntawm qhov tseeb qhov system.
Vim li cas cov tshuab engineering tseem ceeb?
Cov Systems Engineering txheej txheem muab kev nkag siab zoo ntawm cov neeg siv khoom xav tau thiab pab cov neeg tswj hwm kev tswj hwm kev hloov pauv thiab teeb tsa tau zoo los ntawm qhov projectlifecycle. Nws tsis nyuaj kom paub thaum twg System Engineering poob, vim thaum ib yam dab tsi tseem ceeb mus yuam kev itusually ua rau xov xwm ceev.

Logical database modeling suav nrog; ERD, daim duab ua lag luam, thiab cov ntaub ntawv tawm tswv yim rau cov neeg siv; whereasphysical database modeling suav nrog; server qauv daim duab, database tsim cov ntaub ntawv, thiab cov neeg siv cov ntaub ntawv tawm tswv yim
Social engineering yog dab tsi thiab nws lub hom phiaj yog dab tsi?
Social engineering yog lo lus siv rau ntau yam kev ua phem ua phem uas ua tiav los ntawm tib neeg kev sib cuam tshuam. Nws siv kev puas siab puas ntsws los ntxias cov neeg siv kom ua yuam kev kev ruaj ntseg lossis muab cov ntaub ntawv rhiab
Dab tsi yog qhov zoo ntawm txheej txheej rau kev tsim qauv hauv kev khiav hauj lwm qhov system?
Nrog rau txheej txheej, txheej hauv qab yog cov khoom siv kho vajtse, thaum txheej siab tshaj plaws yog cov neeg siv interface. Lub ntsiab kom zoo dua yog simplicity ntawm kev tsim kho thiab debugging. Qhov teeb meem tseem ceeb yog txhais cov txheej txheem ntau yam. Lub ntsiab tsis zoo yog tias OS nyiam ua haujlwm tsawg dua li lwm yam kev siv
Dab tsi yog qhov kev tsim qauv tsim ntawm lub database?
Logical database tsim yog tus txheej txheem ntawm kev txiav txim siab yuav ua li cas npaj cov yam ntxwv ntawm cov koom haum hauv ib cheeb tsam kev lag luam muab rau hauv cov qauv database, xws li cov ntxhuav ntawm cov ntaub ntawv sib raug zoo
Dab tsi yog qhov qub txeeg qub teg Dab tsi yog qhov sib txawv ntawm qhov qub txeeg qub teg piav nrog piv txwv?
Inheritance yog ib txoj hauv kev kom tau txais cov yam ntxwv thiab kev coj cwj pwm ntawm ib chav kawm los ntawm lwm chav kawm. Cov chav kawm uas cov tswv cuab tau txais qub txeeg qub teg yog hu ua chav kawm hauv paus, thiab chav kawm uas tau txais cov tswv cuab tam sim no hu ua chav derived. Inheritance siv IS-A kev sib raug zoo
