SQL has had a hold on databases for years. The relational database model began to emerge in the 1970s and quickly gained traction. Its use cases are so well documented that forty years later, SQL is still the most used type of database. According to db-engines.com, the four of the top five most popular databases are all relational; the only NoSQL database to break through the top five is MongoDB, which recently overtook PostgreSQL's fourth place slot. Some of the top sites out there use SQL to query their data, including Facebook and Airbnb.

SQL is powerful to use, and according to an infographic by Wired, it will still remain as one of the best tools to use well into the future. However, its structure may change slightly in order to deal with new types and sources of data, and distributed RDBM Systems will see a surge in popularity.
