PowerBuilder 10 Major Features
...

3. Object-Oriented Modeling (via PowerDesigner plug-in)

With PowerDesigner as a plug-in, PowerBuilder allows developers to do modeling, code generation, reverse engineering, and code navigation in an iterative manner.

- Modeling and code generation: the developer can create an OOM (Object-Oriented Model) in the PowerBuilder IDE to model applications and then generate the code to run the applications.
- Reverse engineering: the developer can reverse-engineer existing PowerBuilder code and generate class diagrams to provide an overview of the code.
- Code navigation: from generated class diagrams, developers can navigate through classes and objects and open the appropriate PowerBuilder painter by double-clicking a specific object and pointing to specific code.

With these capabilities, PowerBuilder allows developers to iteratively design and code complex applications. For maintenance and enhancement of existing PowerBuilder applications, these capabilities provide developers with tools to understand the code and the structure of the application and make modifications.
