# Introduction

# Introducing Couchbase Lite

###### 

Couchbase Lite is an embedded, NoSQL JSON-document Style database for your mobile apps.

You can use Couchbase Lite as a standalone embedded database within your mobile apps, or with Sync Gateway and Couchbase Server to provide a complete cloud to edge synchronized solution.

##### Work locally . . .

* Couchbase Lite is designed to work with data stored locally and includes

  * The ability to write queries with semantics based on SQL.
  * _Full-Text Search_ queries on documents stored locally.
  * The ability to store document attachments (blobs), for example images or PDF files.

##### Sync at the edge . . .

* It manages data sync automatically through:

  * A replication protocol built over WebSockets to synchronize data with Sync Gateway.
  * A Peer-to-Peer sync implementation to synchronize data between Couchbase Lite clients without dependency upon centralized control.
