What is Drill-Down (Roll-Up)

The Web is increasingly used as a preferred medium for A2C (administration to citizens) and A2B (administration to business) service delivery. An increasing number of government initiatives are aimed at making access to electronic records easier for the general public. For example, the Electronic Record Archives program of the U.S. National Archives and Records Administration is aimed at preserving virtually any kind of electronic record, free from dependence on any specific hardware or software, and at enabling customers to find records they want and to deliver those records in formats suited to customers’ needs (Lake, 2006). This in particular will include records coming from the 2010 U.S. census. International professional associations are increasingly paying attention to public availability of statistical data. For example, the last meeting of the International Association for Social Science Information Services & Technology (IASSIST, 2006) dedicated entire sessions to problems like knowledge and resource discovery, innovative data dissemination systems, and data-intensive Web site design.
