Couchbase Lite for iOS and Android

On Premise In the cloud

Before Couchbase Lite…

•Locally, could use SQLite or Core Data This works well for apps using relational algebra, and/or not data-intensive However this does not suit the needs for mobile developers interested in an

intuitive and flexible data store

•For sync and storage, could use a file-sharing service like Dropbox or iCloud Not an actual database; ownership, insight, and analytics unavailable

•Or alternatively, could use MBaaS like Parse or Kinvey But, it missed out on the offline experience, and we are still very much in an

occasionally connected world; to write a good app, you need to think offline

Couchbase LiteThe only NoSQL Database for Mobile Devices

•Features Ultra-lightweight, secure JSON

database Native support for iOS, Android

and REST/HTML5 Full document, index and

querying and sync capabilities Powerful conflict resolution

Features Benefits

Native APIs Manage your mobile database using APIs optimized specifically for iOS and Android

REST APIs REST APIs provide an alternative access method based on your development needs

JSON support Use a flexible data model designed for mobile object-oriented apps. Adapt to your application needs with immediacy and little impact

Easy sync with Couchbase Sync Gateway Get sync-ready in less than a few lines of code. Focus on application development, not syncing

Peer to peer support via REST APIs

Communicate with nearby devices, even offline, with our REST API-enabled P2P support

Data routing via channels Get users only the data they need for a focused, relevant app experience

Changes Feed

Provides developers visibility and notification into data changes

Indexing and querying for JSON Use powerful secondary indexes to query your data on the device

Authentication plug-ins Use popular existing third-party authentication services like Facebook and Mozilla Person instead of writing your own

Attachment support on device and in the cloud Manage binary data, like photos and large files, separately from your JSON documents for optional, speedier sync

What you get

How does sync work?

Collaborate using Channels

•For each document, you specify a set of channels it belongs to

•For each user or device, you control which channels they can access

•Replicate only a subset of documents down to the device User-defined filter functions Simply lets you know whether a document should be replicated

•And you can authenticate users

Demo Features

JSON / REST interface

-CRUD operations use HTTP verbs

-Works with libraries like jQuery and BackboneLive Query UI Updates

-UI updated to reflect database changes, even for remote changes

-HTTP long poll API to support quick redraw

Collaborate via Cloud-social network login

-programmable sync function for update validation and channel routing

JSON Document Schema

All Todo Lists

•Rendered with HTML and JavaScript

•View query to show all the lists on a device.

•Form submit event creates a document representing a list.

Task List - Items

•Toggle a checkbox

•Add a photo

•Live update

Toggle a Task Checkboxby updating the JSON Document

Uses a familiar REST paradigm. GET and PUT used here.

Live Update UI

Local and remote updates both trigger a database event, used for redraw.

Sign-in to sync and collaborate

•Example uses Facebook, we support a wide variety of authentication option

•Pick from the list of signed in users when sharing
