Big Data Technologies refer to tools and systems designed to process and analyze large volumes of data that traditional methods cannot handle efficiently. These technologies enable organizations to collect, store, and analyze vast amounts of information from various sources, such as social media, sensors, and transaction records. Key components of Big Data Technologies include Hadoop, a framework for distributed storage and processing, and NoSQL databases, which allow for flexible data models. Other important tools include Apache Spark for fast data processing and data visualization software that helps users interpret complex data insights easily.
