    • Data Management Systems support the managing of data assets within an organization.

    Big Data

    • Big Data refers to large volumes of data that cannot be processed with traditional tools and methods.
    • Volume signifies the massive amounts of data generated, moving beyond terabytes to zettabytes or even brontobytes.
    • Velocity highlights the rapid pace at which data is generated, with significant quantities uploaded every minute (e.g., hundreds of hours of video to YouTube).
    • Variety indicates the diversity of data types; 80% of global data is unstructured, ranging from text and images to video and sensor data.

    Systems Thinking

    • A system is an interconnected set of components working towards defined objectives.
    • Business problems can be categorized into "soft" (messy) problems and "hard" problems.
    • Soft problems relate to crises or conflicts, where human factors are prevalent.
    • Hard problems are clearly defined and quantifiable.
    • Systems Thinking employs system characteristics to interpret real-world situations and insights.

    Characteristics of Systems

    • Component: Individual parts or subsystems of a system.
    • Interrelated Components: Dependencies among subsystems that achieve common goals.
    • Boundary: Division between a system and its environment.
    • Environment: External factors impacting the system.
    • Interfaces: Points of interaction between subsystems or between a system and its environment.
    • Inputs: Resources received from the environment to achieve objectives.
    • Outputs: Results returned to the environment after processing inputs.
    • Constraints: Conditions limiting a system's ability to achieve its goals.
    • Stakeholders: Individuals or organizations with vested interests in the system.

    System Classification

    • Systems are classified as open (interacting with their environment) or closed (not affected by environmental changes).
    • Business problem solvers use systems characteristics to explore and analyze holistic business situations, applying systems thinking to understand organizational dynamics.

    Data vs. Information

    • Data consists of factual details; the plural form of datum.

    • Executive Information Systems (EIS): Used by executives to make strategic decisions with data visualization tools.
    • Enterprise Systems (ES): Integrated systems that manage and automate core business processes.
    • End-user Information Systems (EUIS): Systems tailored for use by end-users, providing straightforward access to data.
    • Customer Relationship Management Systems (CRM): Tools for managing company interactions with current and potential customers.
    • Database Management Systems (DBMS): Software for creating and managing databases, facilitating data manipulation and retrieval.
    • Enterprise Resource Planning (ERP) Systems: Systems designed to integrate and manage all aspects of a business's operations.
    • Information Processing Systems: Systems converting raw data into useful information.
    • File Management Systems: Systems to manage files stored on computer systems, ensuring organization and ease of access.

    Big Data Characteristics

    • Volume: Refers to the massive amounts of data generated, often measured in Zettabytes or Brontobytes.
    • Velocity: Speed of data creation, indicated by rapid uploads such as hundreds of hours of video on YouTube per minute.
    • Variety: Different forms of data, primarily focusing on unstructured data, which constitutes about 80% of global data.

    Understanding Systems

    • A system is an interrelated collection of components designed to function together for specific purposes.
    • Soft Problems: Issues characterized by crisis or conflict among people, often requiring qualitative analysis.
    • Hard Problems: Clearly articulated problems that can be quantitatively analyzed.

    Systems Thinking

    • A structured approach to understanding complex issues through the lens of system characteristics and relationships.
    • Recognizes the importance of human factors in system dynamics.

    Data vs. Information

    • Data: Basic facts and entities represented as numbers, words, images, and sounds.
    • Information: Processed data presented in a meaningful context, aiding decision-making.
    • Examples of Information: Timetables, reports, schedules, which organize data for practical use.

    Characteristics of Information

    • Relevance: Importance of the information to the user's needs.
