    Importance of Organized Data

    • The main purpose of maintaining data in an organized manner is to facilitate efficient storage, retrieval, and utilization of data.

    Example of Systematic Record Maintenance

    • An example of maintaining records in a systematic manner is keeping a systematic and organized record of student marks.

    Data vs. Information

    • Data refers to the raw, unorganized facts and figures, whereas information is the organized and structured data that provides meaning and value.

    Database in Computer System

    • A database is useful in a computer system because it allows for efficient storage, retrieval, and manipulation of large amounts of data.

    Data Analysis

    • From the given data about students' marks, we can derive trends, patterns, and statistics to make informed decisions or predictions.

    Database Management System (DBMS)
