Beyond 20/20 is a software tool used to access and view data from different perspectives; pivoting and nesting capabilities make it easy to switch dimensions and show more than one dimension along rows and columns.
Files having the extension ".ivt" (or ".ivt") at the end of the file name can be view using the Beyond 20/20 browser. Statistics Canada data sets distributed via the Data Liberation Initiative sometimes use this format. Statistics Canada also provides a Beyond 20/20 Web Data Server (WDS) which allows their files to be viewed without installing the Beyond 20/20 software.
