Hadoop is an open source distributed processing framework that manages data processing and storage for big data applications running in clustered systems. It can handle various forms of structured and unstructured data, giving users more flexibility for collecting, processing and analysing data than relational databases and data warehouses provide.
For more information, see Apache Hadoop.
