Dictionary• RIA = Rich Internet Applications• JS = JavaScript• Sencha = Tea & RIA JS framework ExtJS• Netzke = Rails marries Sencha by @nomadcoder

Why Sencha?• Best RIA framework (personal oppinion)• Cross platform & consistent architecture• Examples & documentation• Maintained by a company• sencha.com

Why Netzke?• Clean Rails-Sencha interface• Pre-fabricated componentents• You dont have to write it yourself• Maintained & documented• Small user group• netzke.org

Where?• Relational data structure• Many actions per view• Conservative end userReporting, ERP, accounting, admin backends,desktop / Excel replacement etc.

Why Hate It?• Steep learning curve• Mixing server and client side Youll use Firebug a lot...

Most Simple Example
