Classification ntawm cov ntaub ntawv systems

Yuav kom to taub lub ntsiab lus muab zais qab lub ntsiab txhais ntawm "kev faib ntawm cov ntaub ntawv systems", koj yuav tsum qhia kom meej uas systems nyob rau hauv nqe lus nug. Ib txhia tseem nco ntsoov lub zoo kawg nkaus 50s, thaum sib txawv accounting suav (mas nyiaj ua hauj lwm) tau nqa tawm nrog kev pab los ntawm koj laij cov cav tov nrog electromechanical hauv paus ntsiab lus ntawm lub lag luam. Txawm tias muaj tseeb hais tias lawv ua tau zoo tsis yog yooj yim los sib piv uas niaj hnub siv hluav taws xob, tiam sis, simplification ntawm suav thiab cov ntaub ntawv yog ib qhov ceev tshaj tsoos phau ntawv mus kom ze.

Tsis muaj zem uas nyob rau hauv lub 60s los ua cuab kom zoo dua ntawm tas cov siv ntawm xws systems nyob rau hauv kev txiav txim rau optimize tsis tau tsuas yog qhov teeb meem thiab muab xam rau ntawm cov nyiaj hli, tab sis kuj nyob rau hauv ntau lwm yam liaj teb ntawm accounting. Nyob rau hauv 70-80 xyoo ntawm xws systems pib yuav tsum tau siv rau kev tswj kev tswj. Nyob rau hauv lub lig '80s ua tsaug rau cov emergence ntawm high-ceev hluav taws xob kev daws teeb meem, ntaub ntawv nruab pib yuav tsum tau siv los ntawm ntau cov koom haum, tsis hais txog ntawm txoj hauj lwm. Nyob rau hauv qhov tseeb, lub system thiaj li ua hauj lwm rau nqi, thiab raws li ib tug tshwm sim, thaum kawg ua rau kom profits.

Hom ntawm cov ntaub ntawv systems yog kawm nyob rau hauv computer science. Lawv yog ib tug ntawm cov lus qhia ntawm no science. Nws tshuav nws lub npe mus rau lub khoom ntawm kev tshawb fawb - lub ntsiab uas muaj peev xwm cia, nrhiav thiab tsim ntaub ntawv. Tsis tas li ntawd los siv lub peev xwm mus nrhiav thiab ntxiv tshiab cov ntaub ntawv. Cov kev daws teeb meem, raws li tej zaum koj yuav twv, yog hu ua cov ntaub ntawv systems.

Cov uas twb muaj lawm kev faib ntaub ntawv system muaj xws li division los ntawm:

• informatization theem. Tam sim no, feem ntau computer AIS (Automated ntaub ntawv Systems). Lawv coj ib feem nyob rau hauv txhua theem ntawm cov ntaub ntawv ua. Raws li, nws yog lam xav hais tias yog lub lag luam cov ntaub ntawv no ua los ntawm tus neeg (nrog rau koom haum pab pab kiag li lawm xws li cov abacus), ces tus ua hauj lwm tus neeg nrog ib phau ntawv IP;
• siv hom no. Qhov loj tshaj plaws cov neeg sawv cev ntawm no hom - analytical system. Qhov no pab pawg neeg no muaj xws li cov Ias (ntaub ntawv-analytical system), IPA (nrhiav cav), IRS (daws system). Part ntawm tus ciam ntawm lub hom zwj ceeb, raws li ntaub ntawv tshuab yog muaj peev xwm ntawm kev ua tau ib tug ntau yam ntawm kev khiav dej num;
• ntau paub kev faib ntawm cov ntaub ntawv systems siv los ntawm lub architecture. Cov yooj yim tshaj plaws tshuaj - ib lub zos ntaub ntawv system (YOG). Ib tug piv txwv - ua hauj lwm rau ib tug siv hluav taws xob tsis muaj qhov yuav tsum tau rau kev sis raug zoo nrog rau lwm cov IP. Ntau txoj ics, ua rau lub hauv paus ntsiab lus ntawm "neeg neeg rau zaub mov". Lawv siv tag nrho cov network kev sib tshuam muaj ib zaug xwb neeg rau zaub mov. Thaum kawg, faib IP - ib tug multi-tiered network nrog ob peb servers;
• kev faib ntawm cov ntaub ntawv systems cob ntau yam ntawm kev pab raws qib. Model ICS pab kom peb tsim kom muaj ib tug ob-txoj kev pauv ntawm cov ntaub ntawv nrog rau txoj kev tshawb qauv. Los ntawm kev siv ntawm txawv le caag (ICS siv nyiaj txiag, zauv thiab lwm tus neeg. Model), nws tseem tau mus nrhiav tau ib tug xov tooj ntawm lwm txoj kev daws teeb meem. Ib tug tshwj xeeb cov ntaub ntawv - cov kws muaj txuj IP;
• lub tshav pob ntawm kev siv. Paub qhov txawv tswj IC (piv txwv tias yog sib tshooj tsim nyog teeb meem); Kev tswj IC (automated fabrication txheej txheem); EC scientific (kev tshawb fawb thiab thwmsim nrog lub processing ntawm cov kev tshwm sim); kev kawm EC (muab kev nkag tau rau hluav taws xob ntaub ntawv); kev ICS (ua ke ntawm ob peb lub zog).

Classification ntawm cov ntaub ntawv systems ntawm tus kheej cov ntaub ntawv yog ua nyob rau hauv cov saum toj no cov txheej xwm, nyob rau tib lub sij hawm muaj ib tug tseem ceeb sib txawv los ntawm tus so ntawm circuits - qhov yuav tsum tau los tiv thaiv ntaub ntawv tiav. Qhov no system yog ib tug ua ke ntawm hardware thiab software tsim rau koj tus kheej cov ntaub ntawv. Nws yuav cia li tshuaj.
