A fully hierarchical CallWeb

Circum Network is pleased to announce that its flagship Web data collection CallWeb system new supports hierarchical data sets — a feature that places it squarely within the lead category of Web-based data collection tool.

What does that mean? Typically, all data for a project are maintained within a single CallWeb data base. There are times, however, when a more complex structure is more appropriate. Let's take the example of a study on family employment. Part of the questionnaire may deal with the household; another part may request information from each household member. Of course, it is possible to set up a large enough number of blocks of questions to accommodate the largest possible household, but this may not be the most efficient way to collect the information.

That's where hierarchical projects come into play. In hierarchical projects, a master CallWeb project acts as the parent data base (in our example, it would deal with the household). One or more "children" CallWeb projects link into the master project to allow as many children "relations" as is required. In our example, each household member would be a child of the master household project. Each such child relation requires a separate CallWeb project; there can be any number of such relationships within a project and children projects may have children projects of their own. For example, one household could have several household members and each household member could have several jobs.
