Cov ntaub ntawv kaw lus tseem ceeb yog tsim los ntawm tsib yam kho vajtse , software , database, network thiab tib neeg. Cov tsib yam sib xyaw ua ke los ua cov tswv yim, txheej txheem, tso zis, tawm tswv yim thiab tswj. Kho vajtse muaj cov khoom siv nkag / tawm, processor , operating system thiab media devices.
Ib yam li ntawd ib tug yuav nug, dab tsi yog cov khoom ntawm cov ntaub ntawv systems?
Cov ntaub ntawv kaw lus tau piav qhia tias muaj tsib yam
- Khoos phis tawj hardware. Qhov no yog lub cev thev naus laus zis uas ua haujlwm nrog cov ntaub ntawv.
- Khoos phis tawj software. Lub hardware yuav tsum paub yuav ua li cas, thiab qhov ntawd yog lub luag haujlwm ntawm software.
- Kev sib txuas lus.
- Databases thiab cov ntaub ntawv warehouses.
- Tib neeg cov peev txheej thiab cov txheej txheem.
Qhov thib ob, dab tsi yog qhov tseem ceeb tshaj plaws ntawm cov ntaub ntawv systems? Cov yam ntxwv ntawm cov ntaub ntawv system yog computer hardware , software , cov ntaub ntawv, cov txheej txheem thiab cov neeg. Lawv muaj nyob rau hauv txhua qhov system cov ntaub ntawv! cov txheej txheem koj siv los pib qhov kev pab cuam, nkag mus rau koj daim ntawv tshaj tawm, luam tawm thiab txuag thiab thaub qab koj cov ntaub ntawv. koj, tus neeg siv, yog qhov tseem ceeb tshaj plaws ntawm MIS.
Tsis tas li ntawd, 3 qhov tseem ceeb ntawm IT infrastructure yog dab tsi?
Qhov kawg ntawm IT infrastructure tuaj yeem faib ua peb lub ntsiab cov ntsiab lus : network, cia thiab xam. Ib txwm infrastructure muaj nws lub network, cia, thiab xam tag nrho cov tswj thiab txuas nrog hauv kev lag luam thiab muaj ntau yam khoom siv ntxiv (xav txog cov servers loj heev los ntawm 1990's).
3 hom ntaub ntawv yog dab tsi?
Hom Cov Ntaub Ntawv Txheej Txheem: TPS, DSS & Pyramid Diagram
- Pyramid Daim duab ntawm Lub Koom Haum Qib thiab cov ntaub ntawv xav tau.
- Transaction Processing System (TPS).
- Management Information System (MIS)
- Decision Support System (DSS)
- Artificial txawj ntse cov tswv yim hauv kev lag luam.
- Online Analytical Processing (OLAP)

Tus qauv twg yog siv los hloov cov ntaub ntawv kho mob thiab kev tswj hwm ntawm ntau lub tsev kho mob cov ntaub ntawv xov xwm HIS)?
Kev Noj Qab Haus Huv Qib Xya lossis HL7 yog hais txog cov txheej txheem thoob ntiaj teb rau kev hloov pauv cov ntaub ntawv kho mob thiab kev tswj hwm ntawm cov ntawv thov software siv los ntawm ntau tus kws kho mob. Cov qauv no tsom rau cov txheej txheem thov, uas yog 'txheej 7' hauv OSI qauv
Dab tsi yog cov ntaub ntawv thev naus laus zis hauv kev tswj cov ntaub ntawv xov xwm?
Kev tswj cov ntaub ntawv xov xwm (MIS) yog hais txog cov txheej txheem loj siv los ntawm kev lag luam lossis kev lag luam, thaum cov ntaub ntawv thev naus laus zis (IT) yog ib feem ntawm cov txheej txheem uas siv los sau thiab xa cov ntaub ntawv. Cov Ntaub Ntawv Technology txhawb nqa thiab pab txhawb kev ua haujlwm ntawm qhov system ntawd
Vim li cas kem taw qhia cov ntaub ntawv khaws cia ua cov ntaub ntawv nkag ntawm disks sai dua li kab qhia cov ntaub ntawv khaws cia?
Kem oriented databases (aka columnar databases) yog qhov tsim nyog rau kev ntsuas kev ua haujlwm ntau dua vim tias cov ntaub ntawv hom ntawv (kem hom) qiv nws tus kheej kom nrawm dua cov lus nug ua - scans, aggregation thiab lwm yam. Ntawm qhov tod tes, kab oriented databases khaws ib kab (thiab tag nrho nws. kab) contiguously
Dab tsi yog cov teeb meem ntawm kev tswj cov ntaub ntawv hauv cov ntaub ntawv ib txwm muaj?
Nyob rau tib lub sijhawm, qhov kev tswj hwm cov ntaub ntawv ib puag ncig tsim teeb meem xws li cov ntaub ntawv rov ua dua thiab tsis sib xws, cov kev pab cuam-cov ntaub ntawv dependence, inflexibility, tsis muaj kev ruaj ntseg, thiab tsis muaj cov ntaub ntawv sib qhia thiab muaj
Cov ntaub ntawv xov xwm thiab cov ntaub ntawv txheeb xyuas txawv li cas quizlet?
Cov ntaub ntawv txheeb xyuas nthuav tawm cov ntaub ntawv nrog kev tshuaj xyuas thiab / lossis cov lus pom zoo; cov ntaub ntawv xov xwm nthuav tawm cov ntaub ntawv tsis muaj kev tshuaj xyuas lossis kev pom zoo.
