Suitable system organization model?

• repository

• client - server

• control model

• layered model

suitable organization model?

• LAYERED MODEL

• CLIENT SERVER

• REPOSITORY

• MODULAR DECOMPOSITION

TECHNIQUES OF MODULE DECOMPOSITION

(MULTIPLE ANSWER)

• LAYER ORIENTED DECOMPOSITON

• COMPONENT ORIENTED DECOMPOSITION

• OBJECT-ORIENTED DECOMPOSITION

• FUNCTION ORIENTED DECOMPOSITION

-Repository schema

-Share large amounts of data

-Sub systems have no concern about how data is produced

-Centralized management

• REPOSITORY

• CLIENT SERVER

• LAYERED

• MODULAR DECOMPOSITION

ADVANTAGES OF CLIENT SERVER

• Easy to add or

  upgrade server

• Effective network

  system

• Cheaper hardware

• ALL OF THE ABOVE

Also called abstract machine model

• REPOSITORY

• CLIENT SERVER

• LAYERED MODEL

• CONTROL MODEL

TWO TECHNIQUES OF CONTROL MODELLING

(multiple answer)

• real time control

• Centralized control

• Event-based control

• modular decompose control

-Top-down subroutine model

-Sequential systems

choose a suitable control model?

• Call-Return Model

• Manager Model

• Broadcast Model

• Interrupt-driven Model
