Resources in the Summary View

You can choose which resources to hide in the summary view. Hide a resource when the resource contains objects such as staging tables that do not affect overall data lineage. To hide a resource and its child objects in the summary view of data lineage diagrams, enable the

Hide in Summary Lineage

option.

You enable the

Hide in Summary Lineage

option for a resource when you create or edit the resource on the

Load

tab. The

Hide in Summary Lineage

option appears on the

Properties

page. The option is disabled by default. You can enable this option for any resource. When you enable this option, Metadata Manager hides the resource and its child objects in the summary view of all data lineage diagrams.

For example, you have a QlikView report in a universal resource that was generated through the following process:

Data for the report originates from a Greenplum table in a universal resource and an Oracle table.

A PowerCenter mapping transforms the data and loads it to a staging database.

A second PowerCenter mapping transforms the staging data and loads it to a table in a data mart.

You query the data mart to generate the QlikView report.

You want to view data lineage for the report, but you are not interested in the data transformation process that occurs through the PowerCenter mappings or the staging database. You edit the PowerCenter resources and the resource that contains the staging database and enable the

Hide in Summary Lineage

option. You then start data lineage analysis from the QlikView report.

The following image shows the data lineage in the summary view:

The summary view displays the Greenplum and Oracle source tables, the data mart table, and the QlikView report.

To see all of the resources in the data lineage diagram, switch to the detail view.

The following image shows the diagram in the detail view:

The detail view also displays the PowerCenter and staging database resources for which the “Hide in Summary” option is enabled.
