This term refers to extremely large and complex data volumes that are not easy to process with conventional data processing tools. Big Data can include structured, semi-structured and unstructured data that comes from various sources and is generated at high speed. Big Data technologies, such as Hadoop and Spark, enable the storage, processing and analysis of this data. The analysis of Big Data can provide valuable insights that can be used to improve decision making, predict trends, and identify patterns. Although Big Data presents tremendous opportunities, it also brings privacy and security issues that must be carefully addressed to realize the full potential of this valuable resource.
