Developer for Maintenance of Applications
Objective
The objective is to train students who will maintain systems developed with CA Gen. Students will get a good knowledge of CA Gen and the principles of modeling in CA Gen. Starting from the analysis and design diagrams an application is built during the training. All important CA Gen diagrams will be discussed.
On completion the student will be able to maintain a GUI client server, 3270-block mode, batch or CBD application. He will get comprehensive practical skills.
He will be able to start in a CA Gen development project immediately, performing general design and construction tasks.
