    Study Notes

    Introduction to Information System

    • A system is a collection of parts that interact to achieve goals.
    • Information Systems (IS) improve organizational processes, making operations simpler and more efficient.
    • A subsystem is an individual component within a larger system focused on specific tasks.

    Types of Systems

    • Natural Systems: Created by nature (e.g., typhoons, floods).
    • Man-Made Systems: Designed by humans (e.g., transportation systems, education and health systems, computer systems).

    Data vs. Information

    • Data: Raw, unprocessed facts in various forms (numbers, text).
    • Information: Organized and processed data that provides meaning and aids decision-making.
    • Data must be collected and processed to become useful for making decisions.

    Computer System

    • An integrated set of hardware and software working together.
    • Provides necessary components for computing performance.

    Information System Functions

    • Collects, stores, retrieves, processes, manages, disseminates, and analyzes information for operational functions and decision-making.

    Master Data

    • Permanent data stored in IS includes:
      • Customer master data
      • Employee master data
      • Subject master data

    Capabilities of an IS

    • Processes transactions quickly and accurately.
    • Manages significant storage with easy access.
    • Supports decision-making and eases information overload.
    • Facilitates effective communication through networks.
    • Enhances organizational memory and fosters a culture of learning.

    Components of Information Systems

    • Hardware: Physical components (servers, workstations, networks).
    • Software: Programs controlling hardware.
    • Data: Facts that systems transform into useful information.
    • Procedures: Instructions describing tasks performed by users and IT staff.
    • People: Stakeholders interested in the system's functions.

    Computer-Based Information System (CBIS)

    • Combines hardware, software, databases, telecommunications, and procedures for data management.
    • Includes various models of software delivery such as freeware, shareware, and proprietary software.

    Developing Information Systems

    • Involves the creation and modification of information systems, adhering to the System Development Life Cycle (SDLC).
    • System testing is critical for performance assessment.
    • Implementation involves deploying the system after successful testing and user training.
    • Maintenance focuses on reducing operational costs and optimizing performance through ongoing assessment.

    System Development Life Cycle (SDLC)

    • A project management framework outlining stages of information system development from feasibility studies to system maintenance.
    • Key phases include:
      • Requirements analysis and definition
      • System design and development
      • System testing and evaluation
      • System implementation and deployment
      • System maintenance and support.

    Information System Security

    • Involves safeguarding information and systems against unauthorized access, malware, and breaches.
    • Essential for maintaining the integrity and confidentiality of data.
