What is a common advantage of using NoSQL databases?

A common advantage of using NoSQL databases is their flexibility in handling unstructured data. NoSQL databases, such as document stores, key-value stores, and wide-column stores, are designed to accommodate the variability and complexity of unstructured data, which can include text, images, and multimedia content. This flexibility allows for the storage of data in formats that do not require a predefined schema, enabling developers to easily adapt to changes in data formats without the need for extensive data manipulation or migration, which can be time-consuming and costly in traditional relational database systems.

For instance, in a NoSQL database, new fields can be added to data entries without needing to alter the entire database schema or migrate existing data structures. This is particularly important in applications where data requirements can evolve rapidly, allowing for more agile development cycles and the ability to store diverse datasets efficiently.

The other options reflect characteristics of traditional relational databases. High normalization of data is often a goal in relational database design to eliminate redundancy, while strong consistency refers to ensuring that all database users see the same data at the same time, which can be a challenge in distributed systems typical of NoSQL databases. Strict schema enforcement is characteristic of relational databases, where all data must adhere to a defined schema, which can limit
