Consistent with Radicle’s Global Delivery Model, the Define phase and initial Technical Architecture phase – including database design – were performed by the US team.  Detailed design and programming were performed offshore to reduce costs.  Total project effort by both teams over 2 phases of project exceeds effort of 4.75 person years.

Technology employed consists of Java, AJAX, Struts, Hibernate, DOMAPIs, Darwin Media server, FLEX, Adobe Red5 media server, Lucene search engine, Linux, JBoss and MySQL database. Linux and MySQL were chosen by the client to minimize server appliance cost, preserve the flexibility to operate on a Linux platform and develop using an “industry standard” platform.
