Apr 2007, I've been transfered from Professional Services (PS) dept to Product Development team (PDT) after the completion of S&I project. Ecquaria PDT focus on product R&D and innovation, which is always my interest ;) ( You can read more about Ecquaria SOP here )
AJAX was my first assignment in PDT. I was told to champion the R&D and decide how can we move on with it. AJAX is combination of technology, HTML DOM, client-side scripting and XMLHttpRequest object. There are a few popular Ajax toolkits during that time, OpenRico, GWT, YUI and Dojo Toolkit.
As an enterprise product, we always focus on addressing the enterprise concerns, security, scalability & stability. And that's the design philosophy behind the SOPAjax framework. SOPAjax framework focus on server-side development while leaving the client-side user interface widget open in adopting any 3rd party Ajax toolkit.
