ASOLib is a new 4GL library built into the OpenROAD core. It contains components that can assist with design, development, and deployment of applications for the Application Server.

These components can be used to create persistent Application Server session context. This enables pseudo-conversational dialogue between client and server applications and allows the creation of persistent userclass objects associated with a client session.

This approach can help to achieve fat-server/thin-client systems, where the majority of the business logic, however complex, is contained within the server application.
