Study Notes

Data, Information, and Knowledge

  • Data: Raw facts, not inherently meaningful
  • Information: Organized data with value beyond the facts themselves
  • Knowledge: Awareness and understanding of information, deriving insights

Types of Data

  • Alphanumeric: Numbers, letters, and other characters
  • Image data: Graphic images and pictures
  • Audio data: Sound, noise, or tones
  • Video data: Moving images or pictures

Characteristics of Valuable Information

  • Accessible: Easy access for authorized users, in the right format and time
  • Accurate: Error-free, avoid "garbage in, garbage out" (GIGO)
  • Complete: Contains all important facts
  • Economical: Cost-effective to produce, balancing value vs. cost
  • Flexible: Usable for various purposes
  • Relevant: Important to the decision maker
  • Reliable: Trustworthy, depends on data collection methods
  • Secure: Protected from unauthorized access
  • Simple: Not overly complex, avoiding information overload
  • Timely: Delivered when needed
  • Verifiable: Checkable for accuracy, using multiple sources

The Value of Information

  • Enables efficient and effective decision-making
  • Improves organizational performance

Information System (IS)

  • Interrelated components that collect, store, process, and disseminate data and information
  • Aims to meet objectives

Components of an Information System

  • Input: Gathering and capturing raw data
  • Processing: Transforming data into useful outputs
  • Output: Production of information in documents and reports
  • Feedback: System information used to adjust input or processing

Types of Information Systems

  • Manual: Human-powered, e.g., investment analysts drawing charts
  • Computer-Based: Using computers, e.g., Management Information Systems (MIS)

Management Information Systems (MIS)

  • Combine hardware, software, databases, telecommunications, people, and procedures
  • Collect, manipulate, store, and process data into actionable information

MIS Components

  • Hardware: Computer equipment for input, processing, and output
  • Software: Programs that govern computer operations
  • Database: Organized collection of facts and information
  • Telecommunications: Electronic transmission of signals
  • Networks: Connect computers and equipment
