Can NoSQL store structured data?

NoSQL databases can store structured, semi-structured and unstructured data. Their main advantages focus on semi-structured (JSON, XML, not all fields are known) and unstructured.

How is data stored in non relational database?

Should I use a NoSQL or a relational database?

If you want to store relational data, use a relational database. If you need to store "unstructured" data, use a NoSQL store. There is however always a need to have "references" to other records in a NoSQL datastore - similar to a relational store.

Should I use SQL or NoSQL for unstructured data?

If you need to store "unstructured" data, use a NoSQL store. There is however always a need to have "references" to other records in a NoSQL datastore - similar to a relational store. The whole idea is that your application has to do the heavy lifting as far as referential integrity is concerned.
