Architecture for the Real World

Your Data Model

Your business logic

Data Layer

Application Logic

User Interface Screens exposed to the end users

Classic Application Architecture

Idealized Situation

How are your opinions?

What do you like most?

What do you like least?

What kinds of difficulties have you had?

What do you think the real world is like?

Small Problem – Easy Fix

Just lift the car out of water

Initial Disappointment

Bring on Heavier Equipment

Whoops, That too was a surprise!

Guess what’s next?

1st attempt at reinventing the wheel

Reinvent the wheel is tougher than you think

Classic Approach Meets Classic Problems

Too Simplistic

Linear model

Inflexible

Static Input / Output

Either Quality, Time, or Cost

Read my blog - http://www.are4.us/?p=815

Lean Approach – Smart Learning

Data Store is everywhere

Browsers (Chrome, Firefox, IE, Opera)

Mobile devices (Iphone, Android, Blackberry, Windows CE, Symbian)

Adobe Flash Applications

Desktop Applications

Game Consoles,

Everywhere !!!

Meshed Architecture (Macro View )

Community Data Models

Growth of No-SQL DBs

Some Causes

SW developers are not natural born DBAs

Developing a good data scheme is pretty tough

Convince your partner to use your DB scheme is tougher!

DB administration could be a full time job

Backup

Security

Profiles

Etc

Mesh Architecture (Micro view)

PersistentData Store(RDBMS)

High PerfData Services

(No-SQL, In-MemoryCached Objects)

Transient Data

Additional Data Sources

Benefits of Ruby on SF

There are lots of incentive to use Ruby

Tools for building web-apps (ERB, HAML, Markdowns)

Methodology (BDD – Cucumbe, Rspec, Shoulda)

Testing (Webrat, Capybara, Unit Testing)

Ease of Deployment & code version & collaboration (Git)

Extensive Code libraries – Github & RubyGems

Many more

History of Ruby on Salesforce

Version 0 – API era

Version 1 + 2 (REST + SOAP) – Force.com Era

Version 3 – (Pure REST) Database.com era

History of Ruby / Salesforce

Salesforce Social Platform

Example App – Ruby Social

Network Updater

The Datbase.Com GEM

Covers both Sobject & Chatter API

Full CRUD on DDL side

Support:

User-name password

Security token

Oauth Flow

Basic Steps

Use the GEMs

Create a client with Consumer key + secret

Authenticate (3 options)

Materialize an Sobject + set Namespace (module name)

CRUD operation on the object

Form-building attributes

Use the Gem

Add GEMs to Gemfile

gem 'databasedotcom'

gem 'databasedotcom-rails’ (optional)

Run bundle install

Initialize the client

# configure client id/secret explicitly # client = Databasedotcom::Client.new :client_id => "xxx", :client_secret => "yyy"

# configure client id/secret from a YAML file # client = Databasedotcom::Client.new "databasedotcom.yml"

# configure client id/secret from the environment # client = Databasedotcom::Client.new

Authenticate

# authenticate with a username and password client.authenticate(:username => "wayne@manor.com", :password => "arkham")

# authenticate with a callback hash from Omniauth client.authenticate(hash_from_omniauth)

# authenticate with an externally-acquired OAuth2 access token client.authenticate(:token => "whoa-that-is-long")

client.materialize("Contact")

Contact.attributes#=> ["Name", "Company", "Phone"]

ron = Contact.find("rons_id")

puts ron["Company"] #=> "The Olde Company, Inc."

ron["Company"] = "Some New Gig, LLC"

ron.reload["Company"] #=> "The Olde Company, Inc."

ron["Company"] = "Some New Gig, LLC"

ron.save

ron.reload["Company"] #=> "Some New Gig, LLC"

Materialize a SObject ClassCRUD operations

Form-building attributes

Contact.label_for("Phone”)#=> "Phone Number”

Contact.picklist_values("Honorific") #=> ["Mr.", "Ms.", "Dr."]
