ENTERPRISE SYSTEM ,CH4 Flashcards
- ERP Technical Architecture:
The layout of layers where applecations are deployed including
- Servers and desktop
- Interfaces and software Objects
Servers and Desktop
The hardware of systems hosting the applecations
Interfacses and Software Objects
Communcation and oprational elements of the system
Types of ERP Architecture
- Mainframe Architecture
- Two-Tier Client-Server Architecture
- Three-Tier Architecture
4 .Cloud computing Architecture
Mainframe Architecture
Mainframe Architecture is a singal powerful computer handled all processign
Advantage of Mainframe Architecture
- Time option sharing : Unables users to share multiple mainframe’s computing on the same time
- Integration : Collect all enterprise functions into on system
Two-Tier Client Server Architecture
it replaces mainframe computers with powerful PC serveces
client PC coneccted directly to the server through a dedictaed connection
Server role
Manging database ( Store and retrives data)
Client role
Handling apllection logic ( and processing tasks )
Display to the users data then send the user input back to the server

Most modern of ERP use this Architecture
It addes applecation server layer between the (client ) and database server
Application Servers of three tier:
Process the business logic and make communicate between the clients and database

Database Three Tier:
Stores all the ERP data
Ensures ACID properties:
- Atomicity : Transactions are completed fully or not at all
- Consistency : Data is stay valid after a transction
- Isolation :Transactions do not affect with each other
- Durability :Data i saved always even after failure

ERP systems enable change:
ERP allows business to adapt manufaturing and planning methods without changing pyphysical layout or configurations.
Cycle time
Is the time between placing an order and delivring the product , this is important for “make-to-order” product
