Data properties
You can adjust the appearance of data in an asset, such as how it is aggregated or what
the column headings are. If you want these changes to affect all assets, you must make them in the
data asset itself.
Changing how data is aggregated IBM Cognos Analytics assigns a default aggregation type to numerical columns when a data asset is imported. For example, the default aggregation for a column called Age is average. The default aggregation for column called Revenue is sum. When you use a column in a visualization, the default aggregation is used. Modifying the data format Sources pane, you can select a different data format type and specify its properties.Enabling server-side data caching
