Advanced Web Development

  1. 1. Advanced Web Development Software Strategies for Online Applications Rob Stein, Charlie Moad, Ed Bachta The Indianapolis Museum of Art
  2. 2. Purpose of Today’s Workshop <ul><li>You will leave today with tools and techniques for building their own online applications . </li></ul><ul><li>You will understand the overarching concepts and strategies behind building dynamic online applications and some shortcuts to accelerate your development </li></ul>
  3. 3. Outline <ul><li>Web App or Web Page </li></ul><ul><li>Trends in Web Software Development </li></ul><ul><li>BYO API’s </li></ul><ul><li>Bite-sized Web Components </li></ul><ul><li>Collaborative Development </li></ul><ul><li>Drupal Bootcamp </li></ul><ul><li>More… </li></ul>
  4. 4. Web Page or Web Application… What’s the Difference?
  5. 5. Web Pages are Built by Producers <ul><li>They convey a set amount of information </li></ul><ul><li>The creator decides what the information is </li></ul><ul><li>Generally the user consumes the content once </li></ul>
  6. 6. Web Apps are Driven by the User <ul><li>Information presented is dynamic and unknown before hand </li></ul><ul><li>The user decides the information they want to see </li></ul><ul><li>Web applications can be used many times by the same user. </li></ul>
  7. 7. Web Page
  8. 8. Web Application
  9. 9. Web Page
  10. 10. Web Application
  11. 11. The More Things Change The More They Stay the Same…
  12. 25. Attributes of a Web Application <ul><li>CORE COMPETENCIES OF WEB 2.0 COMPANIES: </li></ul><ul><li>Services, not packaged software, with cost-effective scalability </li></ul><ul><li>Control over unique, hard-to-recreate data sources that get richer as more people use them </li></ul><ul><li>Trusting users as co-developers </li></ul><ul><li>Harnessing collective intelligence </li></ul><ul><li>Leveraging the long tail through customer self-service </li></ul><ul><li>Software above the level of a single device </li></ul><ul><li>Lightweight user interfaces, development models, AND business models </li></ul>Tim O’Reilly – What is Web2.0
  13. 26. So what are the keys to building great web applications?
  14. 27. We’re in Luck! <ul><li>People have been building robust applications for over 30 years </li></ul><ul><li>They’ve figured out many smart strategies for building applications that are easy to grow and maintain. </li></ul><ul><li>We’ll be sharing those strategies and techniques with you today and applying them to building great web applications. </li></ul>
  15. 28. Differences from Last Year <ul><li>Last year we spent a lot of time talking about the foundations of creating solid software applications… </li></ul><ul><li>This is still important when you are looking to provide access to your own controlled information to a larger audience </li></ul><ul><li>However… </li></ul>
  16. 29. Differences from Last Year <ul><li>Since last year’s talk software services and API’s / SDK’s of web software has really taken hold in a serious way. </li></ul><ul><li>Building True Museum Applications from SAS Components is not so crazy anymore </li></ul><ul><ul><ul><li>Last year it would have seemed foolish to suggest that Flickr could be used as the basis for a digital asset management system… this year… not so much (Flickr-LOC, machine tags, geotag support and integration) </li></ul></ul></ul><ul><ul><ul><li>How crazy is it to think that we could combine Google Gears, Spreadsheets, Form Creator and Sites to create a simple collection management system? </li></ul></ul></ul>
  17. 30. WebDev 2008 <ul><li>Today, web developers are more like a systems integrator than a hardware manufacturer. </li></ul>
  18. 31. WebDev 2008 <ul><li>The craft of web development is now how you choose to use components to communicate about your content. </li></ul>
  19. 32. WebDev 2008 <ul><li>Skills required are now more about knowing what’s out there and how to structure relationships between components and do the integration pieces needed to bring engaging content to users… </li></ul>
  20. 33. X
  21. 36. That Being Said… <ul><li>There are still many reasons why you should consider building your own API’s and application infrastructure. </li></ul>
  22. 37. Reasons to build your own API’s <ul><li>If you have unique information that others are unlikely to support adequately </li></ul><ul><li>If you care about security of your data </li></ul><ul><li>If you wish to control the distribution of your information </li></ul><ul><li>If a guarantee of service is important </li></ul>
  23. 38. Where’s the API for my data? <ul><li>Strategies for rapidly building an API </li></ul><ul><ul><li>Model-driven development </li></ul></ul><ul><ul><li>Last year == XMLSchema (still valid) </li></ul></ul><ul><ul><li>This year == database as your model </li></ul></ul><ul><ul><ul><li>You most likely already have this model </li></ul></ul></ul>
  24. 39. Object Relational Mappers <ul><li>Object oriented access to a database </li></ul><ul><li>No SQL needed </li></ul><ul><li>Data model changes picked up automatically </li></ul><ul><li>Mostly database agnostic </li></ul>
  25. 40. Object Relational Mappers <ul><li>ORMs have come a long way </li></ul><ul><ul><li>They understand you might want to execute queries directly </li></ul></ul><ul><ul><li>Allow custom method additions to objects </li></ul></ul>http://wiki.rubyonrails.org/rails/pages/ActiveRecord http://www.hibernate.org/ http://www.sqlalchemy.org/ http://propel.phpdb.org/trac/

  63. 78. MVC – Applied to the web <ul><li>View (user interface) </li></ul><ul><li>Page components (HTML, XML) </li></ul><ul><li>Page style & layout (CSS, XSLT) </li></ul><ul><li>Effects (Javascript) </li></ul><ul><li>Model (content management) </li></ul><ul><li>Databases (MySQL) </li></ul><ul><li>Back-end logic (PHP) </li></ul><ul><li>Controller (interaction logic) </li></ul><ul><li>State & API handling (PHP, Javascript) </li></ul>user actions, navigation page & theme selection content updates and requests content requests (AJAX) Web Designer Web Programmer Web Programmer Content Creators Content
  64. 79. How do we make use of MVC? <ul><li>We use content management systems </li></ul><ul><ul><li>Let it take care of the heavy lifting (model code) </li></ul></ul><ul><ul><li>Content creators will be happy </li></ul></ul><ul><li>We use templates </li></ul><ul><ul><li>Templates provide a boundary between controller and view </li></ul></ul><ul><ul><li>Think of templates as an interface, and design accordingly </li></ul></ul><ul><ul><li>Web Designers will be happy </li></ul></ul><ul><li>We have a process: Design, implement, evaluate, iterate </li></ul><ul><ul><li>First, plan out what you want to achieve in phase one </li></ul></ul><ul><ul><li>Divide the work based on skill sets </li></ul></ul><ul><ul><li>Implement and test as you go </li></ul></ul><ul><ul><li>Come together again as a team and evaluate your progress </li></ul></ul><ul><ul><li>Plan your next phase… </li></ul></ul>
  65. 80. Subversion (SVN) <ul><li>An improvement on the concurrent versions system (CVS) </li></ul><ul><li>Allows multiple developers to work simultaneously without overwriting each other’s code </li></ul><ul><li>Basic operations: </li></ul><ul><ul><li>checkout </li></ul></ul><ul><ul><li>add & remove </li></ul></ul><ul><ul><li>update </li></ul></ul><ul><ul><li>commit </li></ul></ul><ul><li>Code developed or updated on a beta installation can </li></ul><ul><li>be quickly reflected in a deployment </li></ul><ul><li>It works for designers too! </li></ul><ul><li>Clients: Eclipse plugin, Tortoise SVN </li></ul>
  66. 81. Bringing in non-technical members <ul><li>In the planning phase: </li></ul><ul><ul><li>Non-techies have great ideas too </li></ul></ul><ul><ul><li>They can also provide great insight for interface design </li></ul></ul><ul><li>In the evaluation phase: </li></ul><ul><ul><li>They will do things you hadn’t thought of </li></ul></ul><ul><ul><li>And they won’t be afraid to let you know… </li></ul></ul>Hey Ed, What if you leave a project you really wish you would have deleted?  Is there any way to return to abandoned projects and delete them for the sake of tidying up?  Or is it easier to create an automated process to delete projects with no files and active members? It would be interesting to put in a kind of drop down list by department where we could then just check off members, rather than typing them in. I don't know if this is possible, but for all that I know it's all magic and anything is possible.
