The application servers are built using Sun Microsystems' revolutionary Java environment allowing Concerto customers to benefit from industry beating cross-platform capabilities and access to a rich market of add-on components and third party products.

In addition to raw Java, PROIV provide a server-side JavaScript engine that is embedded within all our application servers. We have chosen JavaScript as a core technology because it provides a phenomenally productive environment within which to build and prototype e-business applications.

At PROIV, we believe in providing solutions based on open standards. "Open" to us, means being widely accessible by the people who need it. JavaScript represents both a language that is defined by an open standard body (ECMA) as well as one that has a huge following in the developer community.

By providing the option to code in server-side JavaScript, businesses will benefit by having access to a wider pool of developers, who will be far more productive in developing solutions that add value.

JavaScript enables organizations to move to the world of e-business in more manageable steps. The valuable people resources that have nurtured organizations' back-office applications can quickly transition to the JavaScript environment and be productive almost immediately. By utilising these skilled and knowledgeable resources organisation benefit from increased profitability, lower staff turnover, and increased loyalty.

In summary, JavaScript has two key advantages for organisations looking to implement an application rapidly:

JavaScript programmers tend to be more widely available, less nomadic and more reasonably priced than their Java counterparts. Existing in-house programming resources can switch to JavaScript more easily, providing a bridge into the world of e-commerce and Java. Organisations benefit by ensuring their most experienced resources have effective participation in both development and maintenance of key business applications application.

JavaScript has one key speed advantage over other programming languages. The diagram below shows the traditional 4-stage development process, with JavaScript, there is no build phase.

Whilst the individual time savings in cutting out builds are small, the cumulative time savings are enormous, especially towards the end of the project when the number of builds dramatically increases.
