CouchDB helps users store and retrieve data quickly and efficiently either on the cloud or their servers. Based on JSON, it supports binary data and allows applications to write data without locking the database. The databases themselves are arranged as documents rather than interrelated tables, rows and columns.

CouchDB is designed to deliver high performance and sustained reliability. It stores data in documents with revision history to ensure that data, when synchronized, is kept consistent across devices. The database architecture is structured to ensure that problems do not percolate to become major issues.

Key features available in CouchDB on Ubuntu:

• ACID Semantics for fault tolerance.
• Delivers offline first experience.
• Waste space recovery.
• Powerful organizing and reporting tools.
• Clustered single-node database.
• Data redundancy and high availability.
