### SQL vs. NoSQL
191+
192+
SQL is not the only tool for managing and analyzing large amounts of data.
193+
As described above, SQL databases store data in tables using a rigid schema.
194+
This works well for many applications, but larger, more complex projects may
195+
benefit from the more flexible approach provided by NoSQL databases. A common application for NoSQL databases is storing documents and files.
196+
197+
NoSQL databases are diverse, employing a variety of data structures tailored
198+
to specific use cases, but in general provide a scalable way to store, search,
199+
and establish relationships within large datasets that cannot easily be
200+
represented by a rigid, tabular schema.
201+
A more thorough discussion of the differences between SQL and NoSQL
202+
is beyond the scope of this lesson, but curious readers can start with
203+
[this comparison](https://www.mongodb.com/nosql-explained/nosql-vs-sql) by MongoDB, a NoSQL database vendor.
