Data storage is a significant problem in a client based application.
Once the questionnaire form has been completed, it will be submitted for storage and analysis. If your survey contains more than one web page for the questionnaire or may need to be completed by individuals over more than one session, then you will need a process for storing the user's responses from one session to the next or for combining the data entered on several different web pages. There are two ways of performing this function. You can store the data directly on the user's web browser or you can store a reference to the data on the users web browser. In plain English, the data you are storing cannot exceed a total of 4,000 characters.
