What type of data does a NoSQL database primarily handle?

A NoSQL database primarily handles unstructured data, which encompasses a wide variety of data types that do not fit neatly into traditional relational database schemas. This category includes documents, images, videos, JSON objects, and other forms of data that may not have a defined structure or format.

NoSQL databases are designed to accommodate the flexibility of unstructured data, allowing for scalability and performance when dealing with large volumes of diverse information. They are particularly well-suited for big data applications and real-time web apps where data can frequently change and can vary in type and structure.

The other types of data mentioned are not the primary focus of NoSQL databases. Structured data, typically organized into fixed fields within records (like in traditional relational databases), lacks the flexibility that NoSQL models offer. While graph data can be categorized under NoSQL, as it often uses specialized databases to handle relationships between entities, it does not encompass the broader capability of accommodating unstructured data. Tabular data, like structured data, is inherently defined and confined to a specific format, which does not align with the core purpose of NoSQL databases.
