Analyst and Design of Information System

The Characteristic of System
• The component of System
A system is consist of amount the components that be interacted, it’s mean the component are work each other to from the united.
• The Limit of System
The area that limit between one system with the other system or with the outside’s environment. The system’s limit is possible be viewed as the united.
• The Outside’s Environment of System
Whatever the outside of system’s limit that effect the system’s operation. The outside’s environment of system can be benefit or loss that system.
• The Connection of System
The connection’s media between one subsystem with the other subsystem on this connection is possible of the energy’s source flow from one subsystem to other subsystem.
• The Input of System
The energy that be entered to system. The input are caring’s input and signal’s input. The caring’s input is the energy that be entered in other to that system can be operated. The signal’s input is the energy that be processed to get the output.
• The Output of System
The result of energy that be processed and classificated be output that usual from the residu.
• The Process of System
It’s has a part of processer that will change the input be output.
• The Target of System
The system be sure has a goal or a target, if the system doesn’t has a target, so the system’s operation won’t unusual.
The Classification of System
The system can be classificated from several vision, there are :
1. Abstract’s System & Physical’s System
The abstract’s system : The system can be idea that doesn’t appearance physicly (Theology’s System).
The physical’s system : The system that appearance physicly (Computer’s System).
2. Natural’s System & Human Imitation’s System
The natural’s system : The system that occur passing natural’s process , the system doesn’t made by human (circle of earth).
Human imitation’s system : The system that created by human (Human-Machine System).
3. The Specific’s System & Unspecific’s System
The specific’s system : The system operate with attitude that can be predicted.
The unspecific system : The system that future’s condition doesn’t be predicted.
4. The Closed’s System & Open’s System
The closed’s system : The system doesn’t relation and effect the outside’s environment.
The open’s system : The system is relation and effect the outside’s environment.




 The Basic’s Concept of Information
The information likes the blood that flow on the body of an organization. The information’s source data. The data is describe the events and factual united.

 The Quality of Information
• Accurancy : The information must be free from the mistakes and doesn't drifftc of.
• Timeliness : The information that come to receiver mayn’t late.
• Relevant : That information has usual to user.
