Management Information System

. Understanding System
The system is divided into two approaches that can be seen from a systems approach that emphasizes the procedures and systems approach that emphasizes the elements / components.
System seen from the procedure by Jerry FitzGerald, Ardra F. FitzGerald and Warren D. Stallings, Jr. is a network system of procedures that are interconnected, gathered together to perform an activity or to complete a particular target composition (Jogiyanto, 2001).
Based on the elements / components of the system is a collection of elements that interact to achieve the goal (Jogiyanto, 2001).

System vs. Subsystems
Subsystem
Is a system within the system.
Example: The engine is a subsystem of the car system.

Super system
If a system is part of a larger system, then the larger system that is super system.
Example: Department of the SI system, but he was part of the system Amikom college, and Amikom college part of the higher education system and so on.

Based on these definitions can be concluded that:
The system is a set of elements which interact with the same intent to achieve a certain goal.
The main characteristic of a system is oriented to achieve the goal. The purpose of that may be called to create value by combining resources in certain ways. Each system actually has a dual purpose, but one is usually used as the main priority so we need to determine the order of priority. The importance of setting priorities, Because so many goals sometimes those goals can be mutually contradictory.
Example system:

1. Circulatory system : The heart and veins that move blood throughout the body
2. Transport system : Officers, who run the machinery and organization of transportation goods
3. Building the school system : educators, administrators, books and so forth.
4. Computer systems : hardware, software, devices that work together for the common run computer processing.
5. Sound Equipment Systems : that work together to run sound processing.
