BSON
BSON (Binary JSON) is a binary-encoded serialization format used primarily to store documents and make remote procedure calls in MongoDB. It extends the JSON model to provide additional data types such as Date and Binary Data, and is designed to be efficient in both storage and traversal. BSON documents are similar to JSON objects but are encoded in a binary format that allows for faster parsing and richer data representation.
Developers should learn BSON when working with MongoDB, as it is the native data format for storing and querying documents in the database, enabling efficient data handling and complex queries. It is also useful in scenarios requiring binary data storage, date precision, or performance-critical applications where JSON parsing overhead is a concern, such as in high-throughput web services or real-time data processing systems.
