This document provides instructions for merging dimensions from different data sources in Web Intelligence. It describes how to: 1) Sort data objects by query to view objects from different sources together. 2) Select objects with common values like a student ID to merge dimensions and join the data. 3) Create variables as details of the merged dimension in order to display objects from both sources in the same report table. Following these steps allows users to query multiple sources and combine specific data for analysis and reporting.
