Security experts warn that there are some serious security considerations to take into account when deploying NoSQL databases. NoSQL systems do not use the SQL language for queries and are schema-less systems that allow users to change data attributes on the fly.

The typical use case for No.SQL databases is that they contain less sensitive information than the typical use of relational databases.”]
