How HDFS master-slave structure works. A master node called NameNode maintains metadata with critical information, controls user access to the data blocks, makes decisions on replications, and manages slaves. As a result, today we have a huge ecosystem of interoperable instruments addressing various challenges of Big Data.

Databases store key information that powers a company’s product, such as user data and product data. The ones that keep only relational data in a tabular format are called SQL or relational database management systems (RDBMSs). But this distinction has been blurred with the era of cloud data warehouses.
