Yam khoom - oriented tsom xam thiab tsim (OOAD) yog ib txoj hauv kev rau kev txheeb xyuas thiab tsim ib daim ntawv thov , system, lossis kev lag luam los ntawm kev thov khoom - taw qhia programming, nrog rau kev siv visualmodeling thoob plaws hauv cov txheej txheem kev txhim kho software los coj cov neeg koom nrog kev sib txuas lus thiab cov khoom zoo.
Yog li ntawd, lub hom phiaj ntawm OOMD yog dab tsi?
Object-oriented tsom xam thiab tsim ( OOAD ) yog technological mus kom ze los soj ntsuam, tsim ib tug software system los yog lag luam los ntawm kev siv Object Oriented (OO) tswvyim. Qhov tseem ceeb tshaj plaws lub hom phiaj ntawm OO tsom xam yog txheeb xyuas cov khoom ntawm asystem uas yuav tsum tau ua.
Ib yam li ntawd, dab tsi yog object oriented system tsim? Yam khoom - taw qhia (O-O) tsom xam thiab tsim yog ib txoj hauv kev uas yog npaj los pab txhawb txoj kev loj hlob tshuab uas yuav tsum tau hloov sai sai rau hauv kev teb rau dynamic lag luam ib puag ncig. Txhua khoom yog computerrepresentation ntawm tej yam tiag tiag los yog tshwm sim. Yam khoom tuaj yeem yog cov neeg siv khoom, cov khoom, xaj, thiab lwm yam.
Tsis tas li ntawd, kev tsom xam cov khoom taw qhia thiab kev tsim qauv yog dab tsi?
Yam khoom - oriented tsom xam thiab tsim (OOAD) yog ib qho txuj ci mus kom ze siv nyob rau hauv tsom xam thiab tsim ntawm ib daim ntawv thov los yog system los ntawm daim ntawv thov ofthe khoom - taw qhia paradigm thiab cov ntsiab lus suav nrog kev tsim qauv pom.
Dab tsi yog qhov zoo ntawm cov khoom oriented tsim?
Qee qhov qhov zoo ntawm cov khoom - oriented programming suav nrog: 1. Txhim kho software-developmentproductivity: Yam khoom - oriented programming yog modular, raws li nws muab kev sib cais ntawm cov dej num hauv khoom -raws li kev tsim kho. Nws kuj yog extensible, xws li khoom tuaj yeem txuas ntxiv kom suav nrog cov cwj pwm tshiab thiab kev coj cwj pwm.

Kev tsom xam thiab kev tsim qauv yog dab tsi?
Kev ntsuas qauv ua haujlwm raws li kev sib txuas ntawm 'system piav qhia' thiab 'tus qauv tsim'. Hauv cov qauv kev tshuaj xyuas, cov ntaub ntawv, kev ua haujlwm thiab tus cwj pwm ntawm lub kaw lus tau raug txhais thiab cov no tau muab txhais rau hauv architecture, interface thiab qib tsim qauv hauv 'kev tsim qauv'
Dab tsi yog qhov txawv ntawm cov khoom taw qhia cov qauv database thiab cov qauv kev sib raug zoo?
Qhov sib txawv ntawm kev sib raug zoo database thiab cov khoom taw qhia cov ntaub ntawv yog tias cov ntaub ntawv sib txheeb cov ntaub ntawv khaws cov ntaub ntawv nyob rau hauv daim ntawv ntawm cov ntxhuav uas muaj kab thiab kab. Hauv cov khoom taw qhia cov ntaub ntawv cov ntaub ntawv khaws cia nrog rau nws cov haujlwm uas ua los yog nyeem cov ntaub ntawv uas twb muaj lawm. Cov no yog qhov sib txawv hauv paus
Dab tsi yog cov haujlwm hauv kev tsom xam cov khoom taw qhia?
OOAD - Object Oriented Analysis Qhia cov khoom thiab pab pawg hauv cov chav kawm. Txheeb xyuas cov kev sib raug zoo ntawm cov chav kawm. Tsim tus neeg siv khoom tus qauv kos duab. Txhais cov neeg siv khoom tus cwj pwm. Txhais cov haujlwm uas yuav tsum tau ua hauv cov chav kawm. Saib glossary
Dab tsi yog qhov tsim qauv tsim qauv tsim thiab lub cev database tsim?
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
Puas txhais tau tias yog kev sib raug zoo ntawm cov khoom ntawm ib yam khoom thiab lub peev xwm ntawm tus neeg sawv cev uas muab cov lus qhia rau kev siv cov khoom?
Kev them nyiaj yog kev sib raug zoo ntawm cov khoom ntawm ib yam khoom thiab lub peev xwm ntawm tus neeg sawv cev uas txiav txim siab seb qhov khoom siv tau li cas
