Is hadoop a database technology

Hadoop is not a database technology.Hadoop is a distributed systems infrastructure developed by the Apache Foundation.

Users can develop distributed programs without understanding the underlying distributed details. The power of clustering is fully utilized for high-speed computing and storage.

Hadoop implements a Hadoop Distributed File System, or HDFS for short.HDFS is highly fault-tolerant and is designed to be deployed on inexpensive (low-cost) hardware; and it provides high throughput to access the Application data, suitable for applications with large data sets. HDFS relaxes the requirements of POSIX, allowing streaming access to data in the file system.

The core design of the Hadoop framework is HDFS and MapReduce, with HDFS providing storage for large amounts of data and MapReduce providing computation for large amounts of data.
