This was my presentation at the Oct 4th, Dallas Ruby Brigade night. It covers Lean Methodology and using DatabaseDotCom and Ruby Source Code https://github.com/raygao/DallasRubyPresentation

1. Building Social Enterprise with Ruby and Salesforce Dallas Ruby Brigade, Oct 4th, 2011 Presented by Raymond Gao

2. Growth of Cloud Computing & Social Enterprise

3. Growth of Cloud Computing

4. Cloud Computing will be a $ 241 billion mkt by 2020

5. Market Cap of Top Cloud Computing Companies

6. Social Revolution 4 hours per month Web Usage Rest of the Web 2010 2011 Sources: Ben Elowitz, Wetpaint / comScore

7. Facebook Members (Growth of Social Networking) More than 500 million active users over 900 million objects (pages, groups, events and community pages) About 70% of Facebook users are outside the United States 9 Novembre, 2010 2010 IUT Cloud Computing Seminar 7

8. Architecture for the Real World

9. User Interface Application Logic Data Layer Classic Application Architecture Screens exposed to the end users Your business logic Your Data Model

10. Idealized Situation

11. 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?

12. Small Problem – Easy Fix

13. Just lift the car out of water

14. Initial Disappointment

15. Bring on Heavier Equipment

16. Whoops, That too was a surprise!

17. Guess what’s next?

18. An Example DB Schema Source: from Internet

19. Another Example Source: from Internet

20. More Examples Source: from Internet

21. 1st attempt at reinventing the wheel

22. Reinvent the wheel is tougher than you think

23. 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

24. Lean Approach – Smart Learning

25. 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 !!!

26. Meshed Architecture (Macro View ) Community Data Models

27. Growth of No-SQL DBs

28. 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

29. Mesh Architecture (Micro view) Additional Data Sources High Perf Data Services (No-SQL, In-Memory Cached Objects) Persistent Data Store (RDBMS) Transient Data

30. 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

31. History of Ruby on Salesforce Version 0 – API era Version 1 + 2 (REST + SOAP) – Force.com Era Version 3 – (Pure REST) Database.com era

32. History of Ruby / Salesforce

33. Salesforce Social Platform

34. Example App – Ruby Social Network Updater

35. The Datbase.ComGEM Covers both Sobject & Chatter API Full CRUD on DDL side Support: User-name password Security token Oauth Flow

36. 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

37. Use the Gem AddGEMstoGemfile gem 'databasedotcom' gem 'databasedotcom-rails’ (optional) Run bundleinstall

38. 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

39. Authenticate # authenticate with a username and password client.authenticate(:username => "wayne@manor.com", :password => "arkham") # authenticate with a callback hash from Omniauthclient.authenticate(hash_from_omniauth) # authenticate with an externally-acquired OAuth2 access token client.authenticate(:token => "whoa-that-is-long")

40. Materialize a SObject Class CRUD operations 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"

41. Form-building attributes Contact.label_for("Phone”)#=> "Phone Number” Contact.picklist_values("Honorific") #=> ["Mr.", "Ms.", "Dr."]
