14 Linking Project Data Sets

You can link together project data sets that have corresponding attributes.

• About data set links
  You create a link between two data sets by selecting one or more attributes from one data set and associating them with corresponding attributes from another data set. These corresponding pairs of attributes are called a link key.
• Creating a data set link
  You create a link between two data sets by setting one or more corresponding attributes from each as the link key. You can do this from either the Data Set Manager or the Data Set Relationships tab of the data set details footer panel.
• Editing a link key
  You can edit a link key by adding or removing attribute pairs.
• Managing aggregation methods for a linked view
  When you first create a data set link, the attributes in the linked view are aggregated by the default aggregation methods set for their data types. However, you can change the aggregation methods used for individual attributes from either the Data Set Manager or the Data Set Relationships tab of the data set details footer panel.
• Controlling automatic filtering between linked data sets
  Automatic filtering of linked data sets is enabled by default, but you can disable it for individual project pages from the Page Data Settings panel.
