Sales data may be available daily, but the sales person compensation data may only be available monthly. To relate these variables, the data must be brought to the lowest common denominator, in this case, monthly. 9. Data may need to be selected to increase information density. Some data may not show much variability, because it was not properly recorded or for any other reasons. This data may dull the effects of other differences in the data and should be removed to improve the information density of the data.

The fourth element is the data access and analysis part, where devices and applications use the data from DW to deliver insights and other benefits to users. Data Sources DWs are created from structured data sources. Unstructured data, such as text data, would need to be structured before inserted into DW. 1. Operations data include data from all business applications, including from ERPs systems that form the backbone of an organization’s IT systems. The data to be extracted will depend upon the subject matter of DW.
