Versa Platform Architecture
Versa:Platform is a development framework that facilitates the rapid development of effective applications for Government agencies. Versa continuously invests in development tools and methodologies, and uses them internally in many client installations. The result is the ability to rapidly develop scalable, secure, thin client, browser based, W3C/508 compliant applications that meet the technology standards set by nearly every state CIO and federal government agency.
