Lisbon, 27th May 2010 Hernâni Borges de Freitas

Ok, I want a web app !

  Common difficulties:   From the ground - Hard to build and maintain an app from zero.

  From the top - Hard to customize features, look & feel and specially small details.

  Reiventing the wheel - Need to rewrite code/UI between all your projects, usually with worst results than using something done before.

  Rock solid – But hard to maintain and to change when you or your client needs.

  Alone in the dark – when problems occurs hard to understand the problem and correct the problem.

Traditional Receipt

  Use a Framework   Define your models, actions and

controllers and mix up:   RubyOnRails, CakePhp, CodeIgniter,

Symfony, Zend Framework, Django,etc....

  Use a CMS   Features and UI already defined:

  Joomla, WordPress, SharePoint, Ez Publish, etc..

  Node has basically   Type

CCK - Model it !

  Every node type can be seen as a domain class, having attributes (fields).

  Fields can have different types (text, numeric, links, references, media, location coordinates).

  Fields edited by different widgets (drop-down, textfields, media browsers, maps..)

  Fields can be shared between node types, related with other fields and its display can be customized.

Views – Filter and show it !

  Select which entities you want to show.

  Select how do you want to show it (table, list, grid, xml/json/rss output ?)

  Select which fields you want to show.

  Select how do you want to filter entities (type, attributes, terms).

  Powerful query builder for all your information.

Blocks & Panels - Organize it !

  Modules can define blocks.

  Each block can be deployed in different regions, pages and to different users.

  Panels allows you to drag and drop content in your page.

  Almost any content can be dragged anywhere.

Hooks - Extend it !

  Extension available by defining new modules which implement certain hooks.

  Modules inside /sites/all/modules or /sites/default/modules
