Which of the following is NOT a type of NoSQL database? Answer: Relational

A relational database, like Microsoft SQL Server, is NOT a type of NoSQL database. NoSQL stands for "Not Only SQL," meaning it's a database that doesn't use Structured Query Language (SQL) and typically has a more flexible structure than traditional relational databases. SQL databases, on the other hand, are designed with rigid schemas and relationships between tables, making them ideal for structured data but less flexible for rapidly changing data.
