Qhov Tseem Ceeb Qhov Sib Txawv - Daim Duab Sib Txuas Vs Daim Ntawv Sib Koom Tes
Ua ntej tsim software, nws yuav tsum muaj kev nkag siab zoo txog qhov yuav tsum tau tsim. Yog li ntawd, nws yuav tsum tau tsim lub system. Nws tuaj yeem ua tiav siv Unified Modeling Language (UML). Nws tsis yog hom lus programming xws li Java, C. Nws yog siv los ua kom pom qhov pom ntawm qhov system. Nrog rau kev qhia txog Object Oriented Programming (OOP), feem ntau cov kev pab cuam thiab software tau tsim. Nws yog ib tug paradigm uas pab ua qauv ib tug software nrog cov khoom. Cov ntsiab lus OOP xws li kev qub txeeg qub teg, encapsulation tuaj yeem sawv cev siv UML. Nws yog ib qho yooj yim thiab yooj yim to taub. Nws tuaj yeem siv txawm tias tsis yog programmers. Feem ntau, ib daim duab tsis txaus los nkag siab tag nrho cov kab ke. Muaj ntau hom UML daim duab qhia txhua qhov sib txawv. Daim duab qhia kab ke thiab daim duab sib koom tes yog ob daim duab qhia kev sib tshuam. Qhov sib txawv tseem ceeb ntawm daim duab kab ke thiab daim duab sib koom ua ke yog daim duab kab ke siv thaum lub sij hawm sib lawv liag tseem ceeb dua thaum daim duab qhia kev sib koom tes siv thaum lub koom haum khoom tseem ceeb dua. Kab lus no tham txog qhov sib txawv ntawm daim duab kab ke thiab daim duab sib koom ua ke.
Daim duab kab ke yog dab tsi?
Daim duab kab ke yog siv los sawv cev ntawm kev sib cuam tshuam ntawm cov khoom nyob rau lub sijhawm tshwj xeeb. Cov lus thov yog sawv cev los ntawm cov xub tsaus, thiab cov lus xa rov qab yog qhia los ntawm cov xub dashed. Lub thawv duab plaub ntsug sawv cev rau lub sijhawm ua haujlwm ntawm txhua yam khoom.
Daim duab 01: Daim duab qhia ib ntus
Raws li daim duab saum toj no, tus neeg siv khoom, xa lus rau cov khoom lag luam kom pom tias cov khoom puas muaj. Cov khoom lag luam xa lus mus rau cov khoom lag luam kom pom seb cov khoom puas muaj nyob hauv Tshuag. Nyob ntawm cov khoom muaj, cov Tshuag yuav teb cov khoom, thiab cov khoom yuav teb rau cov neeg siv khoom. Tom qab ntawd tus neeg siv khoom xa cov lus them nyiaj rau cov khoom them nyiaj. Thaum kawg, cov ntawv txais tau xa mus rau tus neeg siv khoom. Cov khoom thov, them nyiaj thov. Lawv denoted los ntawm cov xub tsaus. Yog / tsis yog, daim ntawv txais nyiaj yog cov lus xa rov qab. Lawv denoted los ntawm dashed xub. Tus neeg siv khoom siv tau ua haujlwm thoob plaws hauv cov txheej txheem no. Cov khoom lag luam thiab cov khoom lag luam yog nquag pib thaum pib. Cov khoom them nyiaj yog ua haujlwm thaum kawg vim nws yuav tsum tau qhib kom tiav cov nyiaj them poob haujlwm. Zuag qhia tag nrho, daim duab kab ke muab cov ntaub ntawv ntawm kev sib cuam tshuam ntawm cov khoom hauv lub sijhawm tshwj xeeb.
Daim duab kev sib koom tes yog dab tsi?
Daim duab qhia kev sib koom tes tsom rau kev sib cuam tshuam ntawm cov khoom. Nws qhia txog lub koom haum khoom. Ib tug xov tooj qhia txog txoj kev hu ua sequence. Txhua tus lej sawv cev rau txoj kev hu ua.
Daim duab 02: Daim duab kev sib koom tes
Raws li daim duab qhia kev sib koom ua ke saum toj no, cov khoom raug sawv cev siv cov duab plaub. Cov lus yog sawv cev los ntawm ib tug xub thiab ib tug kab zauv. Thawj cov lus yog xaj khoom. Cov lus thib ob yog tau tus nqi thiab cov lus thib peb yog them nyiaj. Ib yam li ntawd, txhua cov lus tau muab tus lej sib txuas. Yog li, tus lej qhia tias txoj hauv kev hu ua ib qho tom qab lwm tus. Cov nqe lus muaj xwm txheej yog qhia los ntawm cov kab lus square. Kev them nyiaj ntawm tus tswv thiab vixaj yog cais cov xwm txheej. Kev them nyiaj los ntawm tus tswv thiab kev them nyiaj los ntawm vixaj yog rau kev them nyiaj. Yog li, lawv raug denoted los ntawm 3.1 thiab 3.2.
Dab tsi yog qhov Zoo sib xws ntawm Kev Sib Tham thiab Kev Sib Koom Tes?
- Ob Daim Ntawv Qhia thiab Kev Sib Koom Tes yog daim duab sib cuam tshuam hauv UML.
- Ob Daim Ntawv Qhia thiab Kev Sib Koom Tes piav qhia txog kev coj tus cwj pwm ntawm lub cev.
Dab tsi yog qhov txawv ntawm Kev Sib Tham thiab Kev Sib Koom Tes?
Sib piv vs kev sib koom ua ke |
|
| Daim duab kab ke yog ib tus sawv cev UML kom pom cov kab ke ntawm kev hu hauv lub kaw lus los ua qhov haujlwm tshwj xeeb. | Daim duab sib koom tes yog UML sawv cev kom pom lub koom haum ntawm cov khoom thiab lawv cov kev sib cuam tshuam. |
| Sawv cev | |
| Daim duab kab ke sawv cev rau kab lus ntawm cov lus ntws los ntawm ib qho khoom mus rau lwm qhov. | Daim duab qhia kev sib koom tes sawv cev rau lub koom haum ntawm cov txheej txheem thiab cov lus xa thiab tau txais. |
| Yog tias lub sijhawm ua ntu zus tseem ceeb, daim duab kab ke tuaj yeem siv tau. | Yog tias lub koom haum khoom tseem ceeb, ces siv daim duab qhia kev sib koom tes. |
Summary – Sequence Diagram vs Collaboration Diagram
Thaum tsim software, nws tsis tuaj yeem pib tsim ncaj qha. Nws yuav tsum tau nkag siab txog qhov system. UML yog siv kom tau txais cov duab nkag siab txog qhov system. UML yog yooj yim dua li cov hom phiaj programming hom lus xws li Java, C ++ thiab lwm yam. Muaj ntau yam UML daim duab uas npog ntau yam. Ob ntawm lawv yog daim duab kab ke thiab daim duab sib koom ua ke. Qhov sib txawv ntawm daim duab kab ke thiab daim duab sib koom ua ke yog, daim duab kab sib txuas yog siv thaum lub sij hawm ua ntu zus tseem ceeb dua thaum daim duab sib koom siv tau siv thaum lub koom haum khoom tseem ceeb dua.
