IBM WebSphere Developer Technical Journal: <comment lines> from Reginaldo Barosa
The EGL language is similar to COBOL, but has elements that are reminiscent of Java syntax, and some concepts that might remind you of objects. That is why EGL, included with WebSphere Studio, is viewed as a path to adopting Java; the difficulty of moving a COBOL developer to the object oriented world and Java is well-known, and EGL helps the transition by being geared toward developers without Java skills.

IBM WebSphere Developer Technical Journal: <comment lines> from Wayne Beaton
The model-view-controller pattern defines three layers in an application. The controller layer translates user requests from the view into messages that the model can understand, and also translates information provided by the model into a form that the view can understand. A common mistake in custom applications is business process in the controller.
