It has a number of tables, but two are important for the questionaire: Node and Strings. Node fields such as Title, Tag and NodeNumber, which are numbers linking to a field in String. It also has fields with RTF (Rich Text) with the questions. The entries in the Node table are a linked list: the field NextChild points to a Node entry which is the child of this entry. Parent points to the upper level of the entry and PrevSibling and NextSibling point to the previous and next question, respectively.
