What term best describes customer comments saved as nested JSON documents in Amazon DocumentDB?

The term that best describes customer comments saved as nested JSON documents in Amazon DocumentDB is semistructured.

Semistructured data is characterized by the presence of tags or markers that separate data elements and enforce hierarchies of records and fields within the data itself, but it does not conform to a fixed schema as structured data does. In the case of JSON documents, the data is stored in a format that allows for flexibility in how the data is organized. This enables documents to have varying structures, which can include nested objects and arrays, making the data more versatile for different applications.

This flexibility allows developers to easily adapt their data models without being constrained by a rigid schema, which is a core advantage of using semistructured data formats like JSON in document databases. The ability to nest elements further enhances this aspect, facilitating complex data representation that aligns well with diverse data requirements.
