SQL is a popular programming language for relational databases that extracts, stores, deletes, inserts, manages, and updates data for structured data and strategic analysis.
NoSQL allows data to be stored and retrieved in forms other than tabular. Data can be stored in structured, unstructured, semi-structured, or polymorphic form.
SQL is used for communicating with databases to store, delete, update, insert and retrieve data, while NoSQL is used to retrieve, store, and manage scalability of databases.
SQL databases support structured query languages, while NonSQL databases does not support declarative query languages.
