So – when will we start to see full blown Web 4GL’s and Application Development Environments?
The first instances are beginning to appear – as DSL – or Domain Specific Languages & Environments. The advantage that Domain specific solutions have, is that they can limit the required level of flexibility over a typical any industry/any application area solution.
So how might this effect the world of eClinical and in particular EDC?
EDC systems today have not generally been built around the architectural capabilities of virtualization of rich client experiences. When a user sits down in front of – Oracle Inform Central Designer for example, they are using a regular software application to create XML (MedML) files that in turn are deployed to a single instance server environment. This approach has not changed much since the early 2000’s. So – whats really wrong with that?
And other companies – are they better?
Medidata have had a fully online build environment for many years, but, the environment is largely a front-end to underlying database tables. Metadata is largely defined in table contents. However it can be exported to an extended CDISC ODM. A table driven approach is good in many ways. It controls what can and cannot be done, and so the scope of potential testing and validation is controlled. The downside is that it limits potential performance to the point and click speed, or, to the speed at which working with external tools apply.
