A Document Store is a type of database designed to store, retrieve, and manage semi-structured data in the form of documents. These documents are typically formatted in JSON, XML, or BSON, allowing for flexible data structures. This makes Document Stores ideal for applications that require rapid development and scalability, as they can easily accommodate changes in data formats without needing a predefined schema. Unlike traditional relational databases, which organize data into tables, Document Stores allow for a more dynamic approach. Each document can have its own unique structure, enabling developers to store complex data types and nested information. Popular examples of Document Stores include MongoDB and CouchDB, which are widely used in modern web applications.
