This topic explains how to associate data sources with an aggregated query. Each association must be registered in a single DataSource node, within the set of queries of an aggregated query. Note that use of the DataSource element here should not be mistaken for the configuration of a data source. For details on how to configure data sources, see Appendix -> Configurations for Aggregated Queries -> Configuring Data Sources for Aggregated Queries.
<DataSource ID="dataSource1">
...optional association configurations...
</DataSource>
When configuring an association, the DataSource node must contain the following required attribute:
•ID: Defines the identifier of a previously configured data source, and indicates that this data source is now part of the aggregated query being configured.
