    Study Notes

    Objectives of RDBMS Study

    • Understand the distinction between data (individual facts) and information (meaning derived from data).
    • Differentiate between a database (structured data storage) and a Database Management System (DBMS) (software for managing databases).
    • Recognize the necessity and benefits of using a DBMS, including efficiency, data integrity, and security.
    • Identify various application areas for database systems, such as finance, healthcare, and social media.
    • Comprehend key concepts of relational database management systems (RDBMS) and their use in organizing data logically.
    • Familiarize with essential database terminology: tables (data structure), keys (unique identifiers), and queries (requests for data).
    • Gain practical skills by creating a table in Microsoft Access.

    Understanding Data and Information

    • Data refers to raw facts or values that lack context or meaning when considered individually.
    • Information emerges when logically related data pieces are organized, providing clear context and significance.
    • Example of data: a flight number. Example of information: a complete set of details about a flight including flight number, date, time, departure, arrival, and fare.

    Example of Data Forming Information

    • A structured table illustrates how various elements combine into meaningful information:
      • Flight Number: Unique identifier for each flight.
      • Sector: Departure and arrival locations.
      • Flight Date: Scheduled date for the flight.
      • Departure and Arrival Times: Specific times indicating travel schedule.
      • Fare: Cost of the ticket for the flight.
    • Sample data entry from the table:
      • Flight A11917 – From Mumbai to Delhi on 12-01-2023, departing at 19:45 and arriving at 21:30, with a fare of 8,910.00.
