“Covers all aspects of Smallworld application development”

MDT has proven to be a very efficient development environment for  GE Smallworld applications.

The multitude of tools available in MDT, both Smallworld specific and Eclipse plug-ins, results in a single IDE that covers all aspects of Smallworld application development and support. I have been using MDT since it was first released and find it to be the most comprehensive development environment currently available for GE Smallworld products.
