Journal of Public Health Management and Practice: March-April 2006 - Volume 12 - Issue 2 - p 119–129

Based on a review of state public health department Web sites, this article describes Web-based Data Query Systems (WDQSs) currently used in 27 US states. In addition, functionalities of selected well-established state WDQSs are defined as major functionalities (11), subfunctionalities (21), and specific functionalities (141), on the basis of a consensus process with participants from states and national organizations in the United States and Canada. Also, on the basis of the consensus process, specific functionalities are categorized as core, enhanced, and expert. Key terms relevant to WDQSs are defined. The information contained in this article should prove useful to public health agencies developing, revising, or evaluating the WDQS.

This article describes Web-based Data Query Systems (WDQSs) currently used in 27 US states and provides an overview of functionalities and datasets in 33 WDQSs available through state WDQSs.

This article is based on the state Web-based Data Query Systems Summit held on March 24–25, 2005, in Providence, Rhode Island. Much of the material relating to the desired WDQS functionalities resulted from the March Summit and the associated telephone and e-mail discussions. The authors thank the participants in the WDQS Summit for their helpful comments.
