What is a key feature of NoSQL databases?

A key feature of NoSQL databases is their ability to handle unstructured or semi-structured data, allowing flexibility in how data is stored and retrieved. They are designed to prioritize scalability and performance, often at the expense of complex querying capabilities found in traditional relational databases.

The option suggesting that NoSQL databases primarily focus on retrieving information encapsulates this feature well. These databases often optimize for read and write speeds, making them suitable for applications that require quick access to large volumes of data rather than executing complex queries that involve joins and aggregations typically seen in relational databases.

Other options do not align with the fundamental characteristics of NoSQL databases. For instance, strong support for complex queries is usually a feature of relational databases rather than NoSQL. The use of multiple tables can be associated with relational approaches that emphasize normalized data structures, while strict data organization is characteristic of databases that enforce schema restrictions, which NoSQL typically eschews for more dynamic schemas. Hence, the focus on retrieval and agility in handling data makes the chosen response representative of the core philosophy behind NoSQL databases.
