OLAP Cubes
Online analytical processing (OLAP)cubes are data structures that the Data Warehouse uses to contain the data you import. The cubes divide the data into subsets, defined by shared dimensions.
A dimension is the descriptive attribute of a measure. For example, a dimension might describe the number of transactions on your site. The number of transactions is a measure. The transaction and the products purchased are dimensions. The following figure shows the relationship between dimensions and measures.

The OLAP cubes used by Commerce Server are created during the unpacking process and are populated and processed for data retrieval when the Report preparation DTS task is run. Storing data in cubes increases the speed of data retrieval when you run Web site analysis reports in Business Desk. The following table lists the Commerce Server cubes and dimensions.
