Advanced Techniques in OpenROAD
OpenROAD Version: 6.2
OpenROAD is a high-productivity low-maintenance 4GL-based object-oriented application-development tool for creating business applications of any type and complexity. It is well-established, with thousands of deployments worldwide.
You will learn:
At the end of this course you will be able to:
- Deal with the range of complex issues involved in using OpenROAD
- Produce applications to the high visual and technical standards required by modern Users and Managers
In this course the key techniques needed for high-quality development in OpenROAD, together with major new OpenROAD features (ActiveX, Tree and ListView fields, etc.) are exemplified and practised, and a set of utilities (unsupported) that greatly simplify key aspects of OpenROAD implementation will be provided to course delegates.
