    Introduction to Big Data

    • Big Data is a massive collection of data that grows rapidly over time.
    • Traditional data management systems struggle to store and process Big Data.
    • The New York Stock Exchange generates 1 terabyte of trade data per day.
    • Social media generates over 500 terabytes of new data daily.
    • A single jet engine can generate over 10 terabytes of data in 30 minutes of flight.

    Types of Big Data

    • Structured Data: Stored in fixed formats, easily accessed and processed. Examples include data in databases and spreadsheets.
    • Unstructured Data: Data lacking a defined structure, like text files, images, and videos. Requires organization before processing.
    • Semi-structured Data: Combines elements of both structured and unstructured data. Examples include XML and JSON.
