As a lightweight, document-oriented NoSQL database engine, Couchbase Lite supports data synchronization and is suitable for embedding into mobile applications.

Lightweight means:

• Embedded – the database engine is a library linked into the app, not a separate server process
• Small code size – important for mobile apps because they’re often downloaded over cell networks
• Quick startup time – important because mobile devices have relatively slow CPUs
• Low memory usage – typical mobile data sets are relatively small, but some documents might have large multimedia attachments
• Good performance – exact figures depend on your data and application

Document-oriented means:

• Stores records in flexible JSON format instead of requiring predefined schemas or normalization
• Documents can have arbitrary-sized binary data, such as multimedia content
• Application data format can evolve over time without any need for explicit migrations
• Language native query builder API provides fast lookups without needing special query languages

Syncable means:

• Any two copies of a database can be brought into sync via an efficient, reliable, and proven replication algorithm
• Sync can be on demand or continuous
• Devices can sync with a subset of a large database on a remote server
• The sync engine supports intermittent and unreliable network connections
• Conflicts can be detected and resolved
• Revision trees allow for complex replication topologies – including server-to-server (for multiple data centers) and peer-to-peer – without data loss or false conflicts

Couchbase Lite provides native APIs for:

• Seamless iOS (Objective-C and Swift), Android (Java), and .NET development
• Frameworks such as Xamarin
• Embedded platforms
