Progress OpenEdge is a high level programming language with latest technical capabilities like Object Oriented development, proDatasets, Database Administration, REST servers in built and so on. This is a highly reliable development platform for critical and high volume data processing. I have been using Progress products since 2012 and I started working on it with Progress 4GL 10.2b. I developed number of applications in large scale (i.e. finance, logistics, production processing and Enterprice resource management)
