Strategy

When an application contains unsupported features, you can encapsulate some of them into PowerBuilder non-visual user objects (NVOs) and deploy the NVOs to the EAServer hosting Appeon Server. These NVOs can be called by Appeon Web applications as well as any other Web application or PowerBuilder application.

This n-Tier NVO support allows the user to program powerful PowerBuilder features into the application. If an existing PowerBuilder application is deployed to the Web, the n-Tier NVO technique can work around a vast number of unsupported features (both browser limitations and Appeon limitations).
