Which of the following describes MongoDB's approach to data storage?

MongoDB's approach to data storage is centered around the use of documents, which are stored in a format called BSON (Binary JSON). This enables the storage of unstructured and semi-structured data, allowing for flexible and dynamic data models. Unlike traditional relational databases that rely on predefined tables and rows, MongoDB’s document structure enables developers to store related data together, offering more versatility in representing complex data relationships.

By using documents, each entry can have varying structures, which is particularly beneficial for applications dealing with diverse data types or rapidly evolving schema requirements. This flexibility allows developers to change and evolve their data models easily without needing extensive schema migrations, which can be cumbersome in traditional database systems.

Additionally, this document-oriented approach facilitates easy retrieval of related data by encapsulating all pertinent information within a single document. Therefore, option B accurately describes MongoDB's core approach to data storage, showcasing its strengths in handling various data types and structures efficiently.
