Difference between SQL and NoSQL

Difference between SQL and NoSQL

- NoSQL databases, or non-relational databases, can be document based, graph databases, key-value pairs, or wide-column stores. SQL databases are known as relational databases, and have a table-based data structure, with a strict, predefined schema required.

- NoSQL (“non SQL” or “not only SQL”) databases were developed in the late 2000s with a focus on scaling, fast queries, allowing for frequent application changes, and making programming simpler for developers. Relational databases accessed with SQL (Structured Query Language) were developed in the 1970s with a focus on reducing data duplication as storage was much more costly than developer time. SQL databases tend to have rigid, complex, tabular schemas and typically require expensive vertical scaling.
