Oracle ATG Web Commerce Business Intelligence includes a data model for use with Oracle Business Intelligence. The data model is an intermediate layer that connects the Oracle ATG Web Commerce data warehouse to the analyses in Oracle Business Intelligence. The data model presents the data that is stored in the data warehouse to report authors and it also defines calculations that are useful in reports. For example, the data warehouse contains records of each visit to your Web sites and the data model includes a calculation that counts the number of site visits and presents the total to report authors.
Each field in the data model includes a description field that explains the source of the data and how calculations are performed. You can read those descriptions while browsing through the data model in the Oracle Business Intelligence interfaces. See complete information about installing and using Oracle Business Intelligence in the documentation for that product (http://www.oracle.com/technetwork/middleware/bi-enterprise-edition/documentation/bi-ee-087853.html).
