Sib txawv ntawm Coupling thiab Cohesion

Kev sib txuas Kev sib haum xeeb
Kev sib txuas tseem hu ua Inter-Module Binding. Kev sib haum xeeb tseem hu ua Intra-Module Binding.
Kev sib txuas qhia txog kev sib raug zoo ntawm modules. Kev sib haum xeeb qhia txog kev sib raug zoo hauv module.

Hais txog qhov no, qhov sib txawv ntawm kev sib koom ua ke yog dab tsi?

Hom Kev Cohesion

  • Functional cohesion (yuav tsum tau)
  • Sequential cohesion.
  • Kev sib txuas lus.
  • Txheej txheem cohesion.
  • Temporal cohesion.
  • Logical cohesion.
  • Coincidental cohesion (Yuav tsum tau tsawg kawg)

Tsis tas li ntawd, ntau hom kev sib txuas hauv software engineering yog dab tsi? Hom Coupling

  • Cov ntsiab lus coupling - modules vam khom rau txhua tus 'cov ntaub ntawv sab hauv lossis lub koom haum sab hauv.
  • Common coupling - modules qhia tib cov ntaub ntawv thoob ntiaj teb.
  • Sab nraud coupling - modules qhia cov ntaub ntawv tawm sab nraud, kev sib txuas lus raws tu qauv lossis ntaus ntawv interface.

Hais txog qhov no, qhov sib txawv ntawm kev sib koom ua ke thiab Connascence yog dab tsi thiab lawv hom dab tsi?

Hauv lus, high kev sib koom ua ke txhais tau tias khaws cov khoom ntawm a code base uas muaj feem xyuam rau ib leeg hauv a ib qho chaw. Tsawg kev sib txuas , nyob rau tib lub sijhawm, yog hais txog kev sib cais qhov tsis sib xws ntawm lub hauv paus code kom ntau li ntau tau. kev sib koom ua ke hais txog txhua yam li cas a ib chav kawm yog tsim.

Qhov txawv ntawm cohesion thiab coupling yog dab tsi?

Kev sib haum xeeb yog qhov qhia txog kev sib raug zoo hauv module. Kev sib txuas yog qhov qhia txog kev sib raug zoo nruab nrab modules. Kev sib haum xeeb yog degree (zoo) uas ib / module tsom rau ib yam. Kev sib txuas yog ib qib uas ib feem/module txuas nrog rau lwm cov modules.
