Study Notes
- Data represents specific facts like numbers and statements
- Information is a collection of data
Characteristics of Information
- Timeliness: Information must be up-to-date
- Appropriateness: Information needs to be relevant
- Accuracy: Information should be correct and precise
- Conciseness: Information needs to be minimal, detailed, and relevant
- Understandability: The format of information is important
- Completeness: Incomplete information leads to bad decisions
System Concepts
- System: Interrelated components working together
- Input: Information users add to the system
- Output: Information processed and displayed
- System Boundaries: The scope of activities within a system
- Subsystems: Every system has subsystems that use resources to meet goals
- Subsystem Interface: Connects each system and subsystem
- System Environment: Receives data from the system
- System Feedback: The system needs feedback to process accurately
Types of Information Systems
