Cameron Purdy, a former Oracle executive and a Java evangelist explains what made NoSQL type database fast compared to relational SQL based databases. According to Purdy, for ad hoc queries, joins, updates, relational databases tend to be faster than “NoSQL type databases” for most use cases.

What is the advantage non-relational database?

The obvious advantage of a non-relational database is the ability to store and process large amounts of unstructured data. As a result, it can process ANY type of data without needing to modify the architecture. So, creating and maintaining a NoSQL database is faster and cheaper.

  • Cassandra.
  • Redis.
  • HBase.
  • Neo4j.

Is JSON a NoSQL?
