What is a characteristic of NoSQL databases?

• A. Built on relational technology
• B. Supports complex queries and joins
• C. Non-relational technology use
• D. Strict schema requirements

Answer: (C)

NoSQL databases are defined by their use of non-relational technology, which sets them apart from traditional relational databases. This non-relational approach allows for greater flexibility in how data is stored, managed, and retrieved. Unlike relational databases that rely heavily on structured data and predefined schemas, NoSQL databases can handle unstructured or semi-structured data, accommodating a variety of data models, such as key-value pairs, document stores, wide-column stores, and graphs. The flexibility of NoSQL databases makes them ideal for modern applications that require rapid scaling and the ability to process large volumes of diverse data types. This characteristic is particularly useful in big data environments and for applications that experience variations in data structure or require quick iterations in development. In contrast, relational databases are built on structured query language (SQL) and require a strict schema, which limits changes and may hinder scalability. NoSQL also typically does not support complex queries or joins to the extent that relational databases do, as they are designed for different use cases that prioritize speed and scalability over complex querying capabilities. Therefore, the characteristic of being non-relational technology use is a fundamental aspect of NoSQL databases.
