JDBC, O/R, HTML, DOM….JDBC, O/R, HTML, DOM….
• On the other side:• Thousands of developersp• Most don’t know these technologies• Most come from 4GL background• Expecting a visual and declarative approach• Don’t have time to learn all these new technologies• Need to focus on their specific application needs• Need to focus on their specific application needs
• How do you make it easy and approachable?
