Agenda

Mobile development strategies

Salesforce Mobile SDK

The “Mobile Chow Finder” application

Technology stack overview• Database.com

• Ruby on Rails

• jQuery Mobile

• Databasedotcom gem

Demo (aka “Show me the code!”)

Native vs. HTML5 vs. Hybrid

Native applications

Pros• Feature rich, look & feel and performance

• Objective-C & Java

• Easy to find applications

• Easy to monetize applications

Cons• Limited to single platform

• Objective-C & Java

• Distribution via Apple App Store and Google Play

HTML5 applications

Pros• A "write one, run many" solution that is cross platform and cross device

• Low barrier to entry - HTML5, CSS3 & JavaScript skills

Cons• Not up to par with the native app experience

“Frameworks”• jQuery Mobile

• Sencha Touch

• jQTouch

Hybrid applications

Pros• Application framework that enables you to build natively installed applications

using HTML, CSS and JavaScript.

• Supports accelerometer, camera, compass, contacts, geolocation, sotification,

storage and more.

• PhoneGap Build – no SDKs to install! Spits out binaries for 7 mobile platforms

• Discover and monetize via App Store and Play

Cons• PhoneGap: Doesn’t look native

• Titanium: Platform specific API via JavaScript for Android & iOS. No HTML or

CSS support.

CloudSpokes HTML5 Apps

Building the “Mobile Chow Finder”

HTML5 application for service members to find the local “Chow Hall”

Database.com

jQuery Mobile

Ruby on Rails

Geolocation

Store favorites using LocalStorage

jQuery Mobile - View

Super easy! Uses web standard HTML5, CSS3, and JavaScript to easily

develop user interfaces for mobile web apps

Framework built on top of jQuery – EVERYONE loves jQuery!

Provides custom events to detect mobile and touch specific actions like

tap, tap-and-hold, swipe, and orientation change (i.e. rotating the device).

We are just building web pages!!

Database.com - Model

A secure, cloud database for building social and mobile enterprise apps.

Slimmed down version of Force.com database (essentially the Setup

section)• Only custom objects (no CRUD UI)

• Apex classes, triggers & workflow

• Identity & user management plus role and profile security

• Oauth2 & REST baked in

Utilize your favorite Force.com tools

Pricing based upon user licenses, records and transactions

Ruby on Rails - Controller

Great for quickly building social and mobile applications

Leverage thousands of open source packages and frameworks to build

amazing applications.

Databasedotcom Ruby gem• Open source ruby client for accessing REST and Chatter APIs

• Supports OAuth2

• ActiveRecord syntax

• Should be called ‘Forcedotcom’ gem

Host the application on Heroku – WINNING!

Let’s code this sucker up!
