Apache CouchDB

Apache CouchDB is an open-source NoSQL database that uses JSON to store data, JavaScript for MapReduce indexing, and HTTP for its API. It is designed for reliability, scalability, and seamless data synchronization across distributed systems. CouchDB is ideal for applications that require offline-first capabilities, multi-master replication, and flexible data models.

Features

• JSON-based document storage
• HTTP/RESTful API for easy integration
• Built-in MapReduce for querying and indexing
• Multi-master replication with conflict resolution
• Offline-first data synchronization
• Fauxton web-based administration interface
• Append-only storage for crash resistance
• Support for binary attachments
• Clustered and single-node deployment options
• Integration with PouchDB for mobile and browser sync
