Can I use SQL for non-relational database?

Question

In practice, "NoSQL" means "non-relational database," even though many of these databases do support SQL-compatible queries. However, the underlying query execution strategy is usually very different from the way a traditional RDBMS would execute the same SQL query.

Can you query a non-relational database?

NoSQL was never about getting rid of SQL; it was about using non-relational data models where they were better suited. Query might not have been the priority for all of them but now we can expect rich query from non-relational databases as well as everything else they have to offer.

Is SQL only for relational database?

SQL databases are table-based, while NoSQL databases are non-relational. This means that a SQL database contains structured data and can perform an analysis using a relational model. A NoSQL database contains unstructured data, which means it cannot be analyzed through predefined models.

Do some nonrelational databases support SQL-based languages?
