The survey module lets you create a new type of web application where you can manage online questionnaires, such as forms to add or modify profile information, subscribe or unsubscribe from an information service. Once answered, the result gets stored in the Database or into the local variables.
They are stored in the Resources > Online > Web Applications node of the Adobe Campaign tree. The data model can be extended dynamically via the answers given to questionnaires. You can view the results in real time, filter the responses, and analyze them using dedicated charts. To learn more about it click here.
