Document stores

Document stores are a type of database designed to store, retrieve, and manage data in the form of documents—typically formatted as JSON, BSON, or XML. Instead of traditional tables with rows and columns, each document is a self-contained unit that can include complex, nested data structures. This flexibility allows for easy management of varied data types and evolving schemas, making document stores ideal for applications needing rapid development, scalability, and unstructured or semi-structured data. Popular examples include MongoDB and Couchbase.
