    Study Notes

    Types of Data

    • Structured Data: Highly organized and formatted data that can be easily stored and searched in a database, such as relational databases or spreadsheets.
    • Unstructured Data: Unorganized and unformatted data that does not fit into a predefined format, such as images, videos, and audio files.
    • Semi-Structured Data: A mix of structured and unstructured data, having some level of organization, but not conforming to a rigid format, such as XML files or JSON data.

    Big Data Analytics Cycle

    • The cycle of Big Data Analytics consists of five stages: Data Ingestion, Data Storage, Data Processing, Data Analysis, and Data Visualization.

    The 3 V's of Big Data

    • The 3 V's of Big Data are Volume, Velocity, and Variety.
    • Volume refers to the large amounts of data generated.
    • Velocity refers to the high speed at which data is generated and processed.
    • Variety refers to the different types of data generated.

    Hadoop

    • Hadoop is a Big Data processing tool that enables the storage and processing of large datasets across a cluster of computers.
    • Hadoop is designed to handle the Volume, Velocity, and Variety of Big Data.
