Abstract: A system and method for providing a question-answer branching session over a stateless network. The invention provides a framework of reusable software objects implementing the creation and execution of any question-answer branching scripts. In the framework, scripts are used for the collection of structured information, surveys, interviews, evaluations, and expert diagnosis from application users. The components are data-driven by script definitions stored in a database. All persisted values, script progress path, and script results are kept in a predefined XML data structure. User interface and reported results are generated from the persisted data and sent to the client software for displaying via extensible style sheet transformation. Script questions are proceeded according to the values collected from previous answers. Script progress can be paused and resumed. Script answers can update token values and contains an additional text field.
