One popular model for NoSQL databases is the document store model. In this model, data is stored as documents, typically in JSON or XML format, and each document can have its own unique structure. This allows for flexibility in the data schema, making it easier to handle unstructured or semi-structured data. Document store databases also often support querying and indexing of the document contents, making it easier to retrieve and manipulate the data. Examples of document store databases include MongoDB and Couchbase. **

SQL databases are relational databases that use structured query language to manage and manipulate data. They are best suited for complex queries and transactions. On the other hand, NoSQL databases are non-relational databases that do not use a fixed schema and are more flexible in handling unstructured data. NoSQL databases are better for handling large amounts of data and are more scalable than SQL databases. **

Yes, SQL can be used to query some NoSQL databases, such as Apache Cassandra and Apache Drill. However, not all NoSQL databases support SQL queries. NoSQL databases typically use their own query languages, such as MongoDB's query language for MongoDB, and Cassandra Query Language (CQL) for Apache Cassandra. These query languages are designed to work with the specific data models and structures of each NoSQL database. **
